Review: A Solid TENS Unit That Works with EMSI Electrodes - About 8 years ago, I was prescribed an EMSI TENS unit. I was sent a second, upgraded unit about 5 years ago. I received EMSI electrodes monthly, so I wound up with a stockpile (6 dozen) of electrodes. About 4 months ago, both units stopped working. With the nerve damage and pain after a foot surgery, I wanted to keep using a TENS unit to slow down the nerve damage, so I tried to buy a new EMSI unit and apparently that requires a doctor's prescription since the EMSI site doesn't have a shopping option. I found a used EMSI unit on eBay for $45, but I wasn't excited about that option. I started trying to find a unit on desertcart that I thought I could use with all those electrode patches and I FOUND IT with this unit. For the cost, I was getting a new unit that could be returned if it wasn't compatible with the electrodes. I've used it every day (3x daily) since it arrived. See the EMSI patches on my surgery site in use. This unit came with 1 pack of electrodes. You can see they are a bit larger than the EMSI patches. The unit has a very good, clear instruction booklet with it. And the unit is easy to use. I like the fact the controls are protected with covers. That prevents accidentally hitting the controls and getting a painful shock. All in all, I would buy this unit, particularly if you have EMSI electrodes you'd like to use. As I'm writing this review, the electrodes are attached to my calf hopefully stimulating blood flow to the nerve-damaged foot.

### ⭐⭐⭐⭐⭐ Great compact Tens & Ems device and easy to use
*by A***R on October 4, 2025*

Instructions are awful and confusing. Check YouTube before operating this device. No real way to know what mode to use, wave length, or in general how to identify what settings to use for pain relief. Again just no directions on what mode to use, or Tens vs Ems. Intensity settings is going to be different for most users. Used on my wife’s leg for knee pain and she did feel it was reducing her level of pain. Buy it, play with the settings, watch YouTube videos. Good quality and pretty harmless but be sure to place pads from 2-6 inches apart for best results. Start at 100 hz, tens, normal, 30 minutes. Set intensity to 2-3 on channel 1 or Channel 2 . Use only one channel and two pads initially 2-6” apart on muscle not bone. Be sure you clean your skin with soap and water and dry before applying the pads. You can also use channel 2 simultaneously and place pads in another area. Intensity should start at 2-3 and increase until you feel comfortable and don’t overdue it the first time. Then perhaps repeat the process in 6-8 hours or the next day. The key to pain relief is the word comfortable and no more. Muscle takes time to heal and the EMS process interrupts the pain signals to your brain providing temporary relief. As the muscle heals and relaxes from the electrical pulses the spasms will subside in time. Remember spasms are your bodies defense mechanism to prevent further injury to nerves and your spine. Your body limits movement around the injured area ie spine, knee, joints, neck or cervical area. Remember stay away from bones and focus on surrounding muscles where contractions take place. If you feel no relief within 4/5 days see a professional. It may be necessary to get an MRI or X-rays. Let pain be your best guide to getting urgent treatment.
