You have full control over your pain relief routine with 20 levels of intensity and a 10-to-60 minute program timer. This is an FDA 510K cleared OTC medical device and comes with a lifetime warranty.
The HealthmateForever HM6G is a powerful unit. Although the translated instructions stink, its operation is easy to understand. Choose from one of six massage programs and an intensity level. I appreciate the power of the HM6G when I need to blast the first hint of plantar fasciitis. This unit is bigger and heavier than most handheld TENS units.
This TENS unit gets right down to business with a big screen, easy-to-use controls and plenty of juice for any pain relief regimen. It is bigger than other units, but fits in a pocket easily. It is not fancy, but will do any job you ask of it.
Lifetime Warranty FDA cleared HealthmateForever TENS unit Pro8AB

- Independent dual channels save time
- Can only change intensity on each channel, not the mode
The Pro-8AB is a very capable electrotherapy device that provides eight modes pain relief for back, neck, joint, shoulder, leg, arm, hands and feet resulting from strain, injury, inflammation or fibromyalgia. It is also one of the easiest TENS/EMS machines to operate with a big, backlit LCD screen and a simple toggle control. It features independent dual channels to customize pain management routines on different areas of the body. This is an FDA cleared Class II OTC device and comes with HealthmateForever’s lifetime guarantee.
The dual-channel feature of this HealthmateForever TENS unit is a big deal. Although you cannot select a different massage mode for each channel, channel intensity is totally under your control. It works great on my lower back plus one shoulder simultaneously. Like other TENS units from HealthmateForever, the higher intensity levels, up to 9, really have some kick. I love the acupuncture massage mode which actually produces the same sensation as an acupuncture treatment.
This unit is another well-built, FDA-approved device from HealthmateForever. The dual-channel feature is a huge plus. If you need to work more than one area at a time, that feature alones saves tons of valuable time. With the lifetime warranty, you cannot go wrong.
truMedic TM-1000PRO Deluxe Tens Unit for Pain Relief
- Completely independent dual channels

- Zipper case too small to hold the unit and all accessories
This new unit from truMedic is designed for versatility and fast pain relief. Dual channels with 20 power levels, easy-to-understand controls and a simple, bright LCD screen make the truMedic TM-1000PRO a pleasure to operate.

It weighs less than five ounces and includes a built-in Li-Ion battery. So, you can take it anywhere and use it throughout all your daily activities.
This was the first TENS unit I bought. It is dead simple to figure out how to use it by yourself even without the well-written manual. All modes are clearly labeled and selected by individual buttons. Intensity is set by push buttons. The small, but clear backlit LCD screen gives you instant feedback on all actions. The side-mounted, 360-degree swivel electrode plugs are tangle-free. Just choose an auto-procedure and one of three massage modes and enjoy. Note the biggest advantage of this TENS unit: auto-procedures, massage mode and intensity settings can be customized for each channel.
Besides being smart-looking, lightweight and easy to set up and use, the TM-1000 PRO’s biggest advantage over competitors are the completely independent dual channels. The build screams quality and it comes at a value price, so there is only one rating possible: 5 out of 5.
Tens Handheld Electronic Pulse Massager Unit
- Battery operated provides complete portability
- Three massage modes: Beat, Knead and Massage
- No adjustment for program duration
This EPM machine from Santamedical provides six pre-programmed routines plus three separate massage modes. Its dual-channel design with separate intensity controls for each pair of pads lets you work two body areas at once. It operates from four AAA batteries. These units are FDA approved and recommended by doctors as one of the best handheld EPM units available. Santamedical offers a 100 percent money back guarantee with each device.
The Santamedical LFM-110 is lightweight, portable and the four AAA batteries provide about 12 hours of massage. The generous, five-foot electrode cables allow placement of each pair on distant parts of your body. Six programs and three massage modes provide 18 different treatment combinations for nearly any kind of pain in muscles and joints. The program timeout is only 15 minutes and not adjustable. My favorite mode was Beat, which provides a half-second pulse at one beat per second.
For convenience and portability, the LFM-110 is a great TENS machine. Its power is impressive for such a small unit. It is completely portable and affordable, which explains its high popularity.
truMedic PL-009 TENS Unit Electronic Pulse Massager
- Lightweight but powerful
- Easy to understand controls and display
- Two channels
- Program, massage mode and intensity same for both channels
- No in-unit recharging of batteries
The PL-009 is truMedic’s brings a hard stop to muscle stiffness, soreness, stress and nearly any type of acute or chronic pain without drugs or side effects. This TENS/EPM massager is their simplest unit, but comes with advanced features. It provides delightful electrotherapy procedures that stimulate muscles and nerves to produce pain relief or relaxation anytime, anywhere.
Weighing just 5.3 ounces with a credit card footprint, it has enough power for a thorough electro-massage on your lower or upper back, shoulders, legs, arms, neck, hands or feet. Simply select one of five auto-stimulation programs, a massage mode, adjust pulse speed and intensity and let it do its work. It is FDA approved and comes with four AAA batteries.
Just as easy to operate as its bigger brother the TM-1000 PRO, the truMedic PL-009 is an effective, affordable pulse massager that can treat two areas simultaneously. The controls are well-labeled and the LCD screen provides clear status. The power levels are thumbwheel-controlled. It is not as versatile as the TM1000 PRO, since the channels are not independent and only five auto-programs are available. A few reviews have noted that the intensity is not as high as Li-Ion systems.
This is truMedics economy TENS/EPM unit. It is superficially similar to the TM-1000PRO without the power or flexibility of that unit. Still, for the money it is quite capable as a pain relief device and thus, represents a good value.
FDA cleared 510K OTC Healthmateforever HM6ML 6 mode Electronic Pulse Massager
- Ease of operation
- 20 intensity settings and six auto-modes
- No auto-programs for specific body areas
This mid-range EPM unit from HealthmateForever features a dual-output design to save time during pain management sessions.

To operate it, select a mode, one of 20 intensity levels and the session duration. As always, this HealthmateForever unit is FDA approved for OTC use and comes with a lifetime warranty.
When you open the box and see how tiny the control unit is, do not lose heart. It is quite powerful for its size. You are unlikely to use the highest intensity settings. Despite being essentially a single-channel unit, you can use it effectively over different parts of the body at once. Choose a mode and intensity and sit back and relax. It can be plugged in while recharging to extend session time. A few buyers experienced unit failures, but the HealthmateForever lifetime warranty is the real deal, so their units were promptly replaced.
The HealthmateForever HM6ML Electronic Pulse Massager packs a wallop in a small package. It offers limited control over massage plus width and frequency, but the six included modes are adequate. Overall, it is an excellent value for the price and capability.
TENS 7000 Unit 2nd Edition Muscle Stimulator
- Plenty of power and duration
- Dual channels
- Five modes to treat any symptoms
- Bit bulkier than comparable models
- Not rechargeable
This unit sells under both the Balego® and ROSCOE brand names. It was designed as an electro-stimulator for relief of pain in muscles and joints for rehabilitation programs. Its powerful 9V battery provides up to 48 hours of treatment. Included are four individual electrodes and an attractive carrying case. It is a superb TENS unit for back pain, inflamed discs or joints, shoulder tension and pain relief in inflamed areas. Not only is it safe, but also affordable, reliable, effective and easy to operate. Pulse width and frequency is adjustable via five operation modes: Burst, Normal, Modulation, Strength Duration 1 and Strength Duration 2.
Electro muscle stimulation for pain management and rehabilitation is a popular technique and the TENS 7000 is one of the most popular units for achieving results. Despite just five “modes”, pulse modulation and frequency are completely adjustable and displayed clearly. Although it is technically dual-channel, channel settings, the only independent selection is the intensity level. The adjustment buttons are protected by a swing-out cover. Overall, this is a very capable unit at an extremely affordable price.
The TENS 7000 is an upgraded version of the popular TENS 3000, which is now hard to find. The build quality is superb although it is not lightweight. It really delivers as an EMS unit, however, and at a price well around $30, you could afford two.
PurePulse Electronic Pulse Massager
- Independent channel settings
- Six auto-set programs, three massage modes
- No internal, rechargeable battery
- 3-ft. electrode wires
For treating muscle stiffness, soreness and other types of muscle/joint acute or chronic pain, nothing is more convenient or safer than this PurePulse EPM unit. Its three healing settings make it the best EMS machine at the price. Two independent channels treat two areas with different stimulation and power levels simultaneously. There are six high-frequency modes tailored for waist, shoulders, joints, legs, hands and feet.
The LCD display tells you everything at a glance including the time of your session, treatment areas and massage mode and pulse settings. It is FDA approved for OTC use and comes with a full one-year warranty.
If you have never used a TENS/EMS machine before, this is an excellent introductory unit. Despite using only four AAA batteries, it outputs plenty of juice. Knead massage mode feels like an actual person’s hands on your back. It is a shame that it is not a rechargeable unit, but finding bulk deals on alkaline cells will mitigate that shortcoming. A few buyers were disappointed that the PurePulse does not penetrate as deeply as their physiotherapist’s high-priced TENS unit, but that is characteristic of EMS machines.
The PurePulse EMS is a hugely popular unit, especially among first-time TENS/EMS/EPM buyers. It is the perfect machine for acquainting yourself with this wonderful pain-relief technology. The PurePulse is effective, save and an excellent value.
iReliev TENS + EMS Combination Unit Muscle Stimulator for Pain Relief & Arthritis & Muscle Strength

Place the supplied large pads directly on painful areas. A wider placement of smaller pads are for larger areas of treatment. Comes with three AAA batteries and a 1-year warranty.
This iReliev TENS/EMS combo unit provides pain relief and muscle conditioning capabilities, which makes it competitive with the best rated TENS unit reviewed here. The independent channels allow customized treatment to different areas at the same time. The EMS P1 setting is for muscle warm-up prior to exercise, P2-P4 are post-exercise muscle recovery modes and P5-P6 improve endurance and strength. For a price point around $90, you might expect a rechargeable unit, but it is still a great value considering the unit’s superior flexibility.
iReliev came up with an excellent design combining TENS pain relief and muscle conditioning EMS. Use it for supplementing exercise routines or dealing with post-exercise stiffness or soreness. Power and flexibility are impressive, but we wish it were rechargeable.
ZT15AB 15 Mode Portable HealthmateForever Mini Handheld
- TENS/EMS with combined 75 auto-programs/massage modes
- Two independent pair-wise output channels
- BeltPlus waist belt for lower back and waist stimulation
- Not rechargeable
When you compare TENS units, you may still feel that any single model from our TENS unit reviews above is not a perfect fit. In that case, the ZT15AB from HealthmateForever may do the trick.
This machine certainly does it all. It is a TENS and EMS machine that combines 15 auto-programs with five massage modes, 30 intensity levels, four output channels and eight electrode pads. It also comes with a BeltPlus waist belt that rhythmically stimulates waist and lower back muscles for a relaxing, toning massage.
Surprisingly, with all that capability it is not a budget buster. It is priced around $60 on Amazon. Naturally, this FDA cleared Class II OTC comes with HealthmateForever’s lifetime warranty.
The ZT15AB is a personal favorite among the devices reviewed here because of its incredible versatility, performance and affordable price. This machine cuts treatment time in half with four channels and eight pads. Channel 1-2 and channels 3-4 are independently adjustable with 30 intensity levels.
Fifteen pre-programmed modes cover specific areas: neck, should, back, elbow, hip, knee, ankle, wrist, feet and hands. Whereas most TENS units provide three massage modes, this one has five: Scraping, Cupping, Tapping, Knead and Acupuncture. In total, you have 75 combinations of programs/modes available.
Twenty-minute default sessions are adjustable from five to 80 minutes. It is an easy-to-read, easy-to-control unit with a big LCD display and toggle control. Its only minor drawback is it lacks an internal Li-Ion rechargeable battery.
It should be no surprise that this unit gets 5 stars all around. It has double the pads of other TENS or EMS units, dual channels, 75 program/mode combinations plus that comfortable, effective waist belt. At around $60, this is the highest value TENS unit we have ever reviewed.

Types of TENS Units
TENS vs. EMS (Electrical Muscle Stimulation) Devices
TENS and EMS devices are quite distinct. Both provide electro-stimulation, but a TENS unit stimulates nerves while an EMS unit is designed to stimulate muscles.
TENS uses high and low frequency current pulses in a small range around 100ma. An EMS unit utilizes cycles that induce muscle contraction and relaxation at various intensities from one to 130Mh. These cycles improve muscle blood flow while decreasing inflammation. Whereas TENS units are primarily for pain management, an EMS unit reverses muscle atrophy and retrains previously paralyzed muscles.
TENS vs. Electronic Pulse Massagers
Between a TENS units and an Electronic Pulse Massagers or EPM, the difference is often without distinction. Strictly speaking, a pure TENS unit supplies only nerve ending stimulation while the electronic pulse of an EPM causes muscle contraction as well. Many TENS units, such as the affordable Prospera Electronic Pulse Massager do both. Electronic pulse massage is different than the action of massage chairs, however. The massage in the best electric massager is mechanical, whereas the massage from the best pulse massager is electronic.
TENS for Home Use
TENS units for home use are often a bit larger, more powerful and have more wires, which might make them more obtrusive or uncomfortable for portable use. Home machines often come with long cables or back belts. For instance, the HealthmateForever TENS Unit Pro8AB 8-modes Pain Relief Electrotherapy Device, may be the best TENS home unit on the market.
Portable TENS Devices
AccuRelief portable TENS units are a favorite of folks on the go. They are lightweight and easily fit into a shirt pocket or handbag. They make a wireless system and a mini-TENS unit with only two tiny stimulation units. The unit uses a single 3V CR2032 coin battery to operate. That might be the best portable TENS unit, but the Homedics Rapid Relief Electronic Pain Relief Pad is, incredibly, even smaller.
