TENS 7000 2nd Edition Digital TENS Unit Review 

TENS 7000 2nd Edition Digital TENS Unit

October 25, 2019

Since the beginning of time, people have been searching for ways to effectively manage pain. Pain management is a constant problem, and everyone eagerly anticipates the next breakthrough or experiment to see if there is some brilliant discovery that may work better than the last.

One popular pain management system on the market today utilizes focused and measured electrical pulses to help decrease pain and produce more endorphins. A device called Transcutaneous Electrical Nerve Stimulation (TENS) delivers these electrical pulses along nerve strands and across the surface of the skin. Through the use of these electrical pulses, pain signals don’t reach the brain, and pain is alleviated.

But what exactly is TENS treatment? How does it work? And, most importantly, is it safe?

We tried the TENS 7000 2nd Edition Digital TENS Unit to see how good of a product it is, test how well it works, and confirm if it helps in effectively treating pain. 

What is TENS?

TENS is a non-invasive pain management therapy using low-voltage electrical currents. Self-adhesive electrodes or patches for delivering the electricity are placed on the body depending on where the pain is. Then, a machine delivers carefully measured low-voltage electric shocks through the fibers of our nerves in regular “pulses.”

These currents then get to work by blocking pain signals before they’re sent to the brain, thus decreasing pain in our bodies. At the same time, they also stimulate the production of endorphins, the body’s natural pain relievers.

People undergoing TENS therapy use a small, portable TENS machine. In some cases, its usage and settings can be pre-determined by a doctor or a physical therapist.

The TENS 7000 is an effective, budget-friendly, over-the-counter TENS unit. Through this machine, you can get the same type of electrotherapy used by doctors and physical therapists in the comfort of your own home, office, or school. While it is still best to consult with them before using electrical stimulation, the TENS 7000 can be purchased without a prescription.

The TENS 7000 was established in 2008 for clinical use. The machines are built to be portable and easy to transport so you can get your treatments at home or on-the-go. The machine is a favorite among industry professionals and is best used for common ailments in areas such as the back, neck, shoulder, elbow, leg, and foot.

It comes complete and ready to use out of the box with:

  • 2 lead wires
  • 1 pack of 4 reusable premium electrodes (pads)
  • one 9-volt battery
  • a fully detailed instruction manual and quick start guide
  • 1 hard carrying case for transport and protection
  • warranty registration

The machine is equipped with several features and accessories that make it easy to use and effective.

Using the TENS 7000

Usually small and compact, TENS machines are simple enough to operate and maintain. However, they shouldn’t be used if you have a medical condition or injuries without first consulting your doctor or physical therapist. Once you have cleared it with the professionals, using the TENS machine is quite simple and can easily be handled in the comfort of your own home.

This small portable machine packs a punch and provides users with everything they need in a TENS therapy machine. The TENS 7000 has several settings that can be adjusted and customized, but it is easy to use thanks to the comprehensive instruction manual, which goes over all the basic features and functions.

TENS 7000 Device

The device itself is simple and functional. It is well-built, and despite being made of plastic, the unit still feels durable and sturdy. The belt clip on the device is very useful when you need to have your hands free during treatment. It comes with two long cables to reach all desired areas. Lastly, the device comes with a protective hard case, which is good for home storage or for when you’re traveling.

Available Modes and Programs

The TENS 7000 has five modes to choose from, namely Burst, Normal, Modulation, Strength Duration 1, and Strength Duration 2. These allow you to decide how you want the pulses delivered.

Alongside these five modes, the machine also has three other program settings you can adjust as needed including intensity, pulse width, and time duration. You can control the level and amount of pain relief by adjusting any of the following controls:

  1. Intensity – You can toggle this control depending on your tolerance for the electric stimulation.
  2. Pulse width – In principle, if you want to experience a stronger electrical stimulation, you can toggle the pulse width higher. Different pulse widths can stimulate various nerve groups. Unless otherwise instructed by your physician or physical therapist however, the recommended setting for the pulse width is at 70 to 120 microseconds.
  3. Time Duration – This refers to how quick the treatment will last. You can toggle the settings from one minute to an hour or set the device at “continuous.” This is handy as other devices have built-in automatic shut-off features.

When used properly, there are no major side effects or risks involved with the use of a TENS machine. In very rare cases, a rash may appear, but these are quite minimal.

The combined modes and settings allow you to have complete control over your therapy session. Many other machines on the market don’t offer that level of control, and users have to make do with the settings that are already present and available.


You can control the intensity of the TENS device using two control knobs, which allow you to toggle the stimulation power of each channel. The device has an intensity range of 0-100mA in 10mA increments. This gives the users a full range of intensity to choose from. For beginners, it’s always best to start at the lowest level and work your way up. The best part is it has a protective cover that conceals the unit’s buttons, preventing you from hitting them during your session and accidentally changing your settings.

Channels and Unit Pads

The TENS 7000 is dual channel, like the majority of TENS machines. The device comes with four-unit pads that are self-adhesive and multi-use. You can use either two or four pads at a time depending on the severity and location of the pain. After several sessions, they do begin to lose the stickiness, and you may need to buy replacement pads. We would have liked to see the product come with an extra set of pads, but its current set seems reasonable for its price point.

The TENS 7000 is extremely compact and handy for travel. It measures 3.98 inches (L) x 2.4 inches (W) x 0.96 inches (H). This makes it smaller than several mobile smartphones in the market today. It’s also fairly lightweight. At 5.29 oz, it weighs just a little heavier than a phone. It’s truly a portable device — easy to pack up and bring to school or work.


The unit is not chargeable and runs on one 9-volt battery. It would be nicer if it was chargeable, but for its price, this is hardly a deal-breaker. A good workaround is to invest in rechargeable 9-volt batteries and a charger to mitigate the costs of replacing the battery. The battery that the unit comes with lasts for 10 sessions, with the power remaining constant. However, once it weakens, you’ll have to increase the power to maintain intensity. Batteries typically last for 48 hours of continual use.

For the features and functionality of the TENS 7000, its price can’t be beat. It’s considerably lower than other machines offering similar capabilities. The TENS 7000 gives you the best pain relief with the most bang for your buck.


The TENS 7000 comes with a 1-year warranty that covers parts and labor for the machine. This ensures that you don’t have to worry about problems or technical difficulties in the first year of use.

Is the TENS 7000 Effective?

TENS isn’t a cure-all for pain and thus, shouldn’t be viewed as such. The pain relief product states that clinical trials on its effectiveness have garnered positive results when it comes to acute pain.

TENS therapy may be used for different kinds of pain such as menstrual, labor, post-surgery and recovery, joint, neck, and back. In addition to this, TENS treatment may also have beneficial pain management effects for sports injuries, arthritis, endometriosis, fibromyalgia, multiple sclerosis, and diabetic neuropathy, amongst others.

Many users have also expressed that TENS machines are effective in helping them manage their pain. The feedback from users appears overwhelmingly positive, several of whom recounting stories of their TENS sessions. Feedback ranges from users with chronic back pain to users with more complex kinds of pain such as fibromyalgia.

TENS currently serves as a low-risk pain relief option for many individuals. The United Kingdom’s National Health Service notes the device as a viable and safe treatment option to use in conjunction with other similar medical treatments. If you have pain you need to manage, a reliable TENS machine is an excellent and low-risk tool to have at home.

What Do People Think of the TENS 7000?

The TENS 7000 is budget-friendly and full of special and functional features, but the question remains – does the product work? By testing the TENS 7000, we found that the treatment did relieve our muscle pain. We used it for several sessions, and after each one, we noticed that our muscles felt more relaxed. This was especially true for the lower back muscles.

TENS 7000 users have noted some of the same benefits after they used the product.

Benefits to Users

A common comment among consumers seems to be that the product greatly reduces the effects of localized pain, tight muscles, and muscle spasms. One user recounted using the TENS 7000 to help with shoulder pain, while another used it to ease ankle, rib, and back pain. They mentioned how the device accelerated healing when used in tandem with ice/heat treatment and proper rest.

Aside from this, some commended the product’s adequate and simple setup. One user was satisfied with the product that they bought another one to treat multiple areas at once. With its many features, such as its compact build and sturdy belt clip, the TENS 7000 seems like an overall affordable and versatile product.

Other advantages that consumers noted were:

  • Vast array of treatment settings
  • Highly portable
  • Easy to handle, even for first-time users
  • Hand carry case is an added perk

FAQ: Warranty and Contact

We did observe some users who claim to have issues with the company’s contact information and were thus unable to reach customer support. However, the TENS 7000 lists the company’s phone number and email address in both their website and quick reference guide for those with support inquiries.

There were also a few users who said that their device stopped working after a couple of months. TENS 7000 issues a 1-year warranty for users. If you experience issues with your TENS 7000 device within the warranty, you can have it returned for a replacement.

Our Conclusion

After road-testing the TENS 7000 2nd Edition Digital TENS Unit, we found a couple of things that we liked about this compact and durable machine. Some of the advantages that we observed include:

  • Durable and sturdy build
  • Long cords can reach all areas
  • Several modes and programs to choose from
  • Full range of intensity levels
  • Flexible time settings
  • 1-year warranty
  • Very budget-friendly

At the end of the day, no TENS unit is a miracle worker, and it can’t take away all of your pain immediately. But it can help alleviate it, and with continued use, you will see better results.

Would we recommend this product? Definitely. With its wide range of features and adjustable controls, this is the best TENS unit on the market today at this price point.
