This is NOT A TOY! I get treated by my chiropractor every month with a professional TENS unit for Sciatic Nerve pain. This does almost as good as his Professional Equipment...

I first read many reviews before deciding. It arrived earlier than scheduled, it comes with everything it indicates. I can't believe the quality for how cheap it is!!!

Tens 7000 is probably one of the best tens unit available in the market as durable and feature rich tens machine for a cheap price.

 Just look at it’s innovative design. Not only it’s one of the most powerful tens unit available on the market ( with intensity of impulses going up to 100mA ), but it’s also one of the most versatile one out there. With multiple settings and easy user controls. It allows you to manually adjust pulse and width of impulses.


Tens 7000 Features


It offers 5 in-built modes and also offers users the ability to self customize these modes.

Burst Mode

In this mode low rate impulses are sent, the frequency is not adjusted by the user, but rather by the instrument itself. It’s a combination of conventional tens and low rate tens.

Modulated mode

In this mode the device tries to continuously cycle the impulses to prevent nerve accommodation. Here users need to be careful with the intensity knob.

Strength-Duration Mode

This consists of alternating patterns of width and modulation increasing or decreasing. While when one parameter increases, the other parameter decreases.

Tens 7000 pads

The pads which it comes pre packed with aren’t the best in quality. We recommend investing in tens 7000 replacement pads. We have a detailed article on tens replacement pads here. We also recommend using electrolytic gel on your skin while using tens for older pads. And we also recommend using a presperent on your skin. As sweat is the main thing which lessens the pads life.

Tens 7000 Recommended Settings

We’re not so sure what advice to give on this topic. Because every patient will have different requirements and needs. But what we do suggest is that keep the current level low and slowly increase it and see the affect. And make sure your muscle do not twitch. Play around with the modulation and width settings and see what suits you best.

Detailed Pros And Cons


It costs just about just $26 dollars, which is very cheap for a tens unit, as high end tens units can cost as much as $100s dollars. But what’s really good about it, that even in such a small price tag, it’s fully loaded with so many features that it’s very surprising. It’s body structure is hard and well build and it’s one of the most powerful tens unit in the market. With current level going up to 100 mA.

Rigid Body:
It’s a sturdy tens machine. It can survive falls and not take damage. Which makes it more handy and useful for carrying it around. Unlike other plastic models out there, it’s metal body provides it with protections.

Carrying Case:
It comes with a carrying case. The case is foam covering from the inside. So even if you drop the case, the foam cushions the fall and avoids any damage going to the tens unit. This helps to save and protect your investment. Few tens unit come with a carrying case.

Dual Channel:
You can simultaneously attach tens machine pads at two different target pain areas on your body. So you can simultaneously get pain relief on two different areas on the body. What’s more better that each channel’s intensity is independent of one other. And you can fine tune them by using the knobs.

Multiple build in modes:
Comes with build in modes. Useful for patients who want to instantly get therapy without going into the nitty gritty of tens unit. Even though the number of modes is less, but it’s still a decent number considering the price tag.

Mode Customization 
This is that one feature which makes it very special. Because this lets you create your own modes and you can customise them in anyway you want. This is great for therapists who wish to use tens unit on you and also for patients themselves. As it gives them control over the device.


Not Rechargeable:
After a while the 9 V battery will be finished and you’ll continuously need to invest in more batteries, which isn’t a good thing. So rather buy rechargeable batteries on your own.

Low quality pads:
The pads are definitely not the best quality, but they’ll still get the job done. However, if you want to maximise the life of these pads. Then what you can do is use antiperspirant. Because sweat is the main factor, which lowers the life of your tens electrodes.

Device Breakdown

2 Channel Knobs:
When you turn any channel knob clockwise, it switches the channel on, but as you further turn it. It increases the current intensity. On the other hand, if you turn the knob completely backwards, it switches off the channel.
Both channels are independent of each other so you can have different magnitude of currents on different pads.

2 Input Channel Slots:
Here you plug in the pads.

Mode Button:
Pressing it changes the mode. We’ll cover each of these in depth later in this article.

Set Control:
You can use any settings to tweak.

Increase or decrease the value of a particular setting.

Allows you to set the timer for your therapy. You can set the timer from 1 minute to 1 hour. And there also will be a 1 minute countdown before it begins.
