- Reviewed in Canada on May 30, 2025Verified PurchaseWell made unit. Able to customize settings - Hz, Amplitude, Time, Microseconds for both TENS and EMS. Dual channel which saves time when treating more than two areas - up to four.
- Reviewed in Canada on June 21, 2025Verified PurchaseWork very well just as described
- Reviewed in Canada on April 22, 2025Verified PurchaseVery happy with this purchase. Easy to use and provides relief from an injury.
- Reviewed in Canada on June 24, 2025Verified PurchaseI am a mobile physiotherapist and I bought this unit to keep in my bag as I travel to my clients' homes. I don't use TENS very often with clients but it's nice to have it if I need an extra option for some pain control. I bought it about 10 months ago, have maybe used it 3 or 4 times and it is now no longer working - tried fresh batteries and playing around with all the settings... Unfortunately, I am well past the return time frame window and I can't seem to find any info re warranty.
UPDATE - I was able to get through to the company through the 鶹 app. They responded very quickly and are sending me a replacement unit. I have amended my review from 1 to 3 stars. We’ll see if the replacement lasts longer
- Reviewed in Canada on December 11, 2024Verified PurchaseI bought a different manufacturer option a few months ago and it has already working properly. This unit arrived yesterday and I’ve already used both the TENS & EMS settings a few times. It works so much better and the pain relief was immediately noticeable after a 30 minute session. Hopefully this continues.
My only complaint so far is that the pads aren’t very sticky at all. I followed the instructions precisely but they do not want to stay adhered to my skin.
- Reviewed in Canada on July 15, 2025Verified PurchaseI got this to supplement weekly physio for an injured back. While I don't see much purpose for all the different modes, it definitely helps. I tend to just pick the SD or ems functions. The only downside is it'd be nice to see a mA counter, as the macho e I use at physio has one, and the do for sake for twns, mA is a better measure.
