Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.

- Reviewed in the United Kingdom on 18 October 2024Colour Name: BlackVerified PurchaseThis is honestly one of the best TENS Machines out there at the price point. The pads that come with it are very sticky and I tend to use it quite a bit. It's battery is easily charged using the supplied USB-C cable, and lasts a long while. It's quick and easy to use, as well as being highly configureable. The nicest part about it is that unlike cheaper TENS units I've owned and tried, this machine doesn't have the "sharp-stabby" feel which I'd put down to very good power supplying and monitoring. This also goes very high and hence can help with some of the worst pain. It can be locked too, hence making this a very pocketable unit.
- Reviewed in the United Kingdom on 30 April 2025Colour Name: BlackVerified PurchaseEasy to use, easy to set up, a good selection and size of sticky skin contact pads, for every purpose or muscle size. It's amazing at easing the pain in my neck and shoulders, massage first then use the electric impulse to finish off. Charge lasts for ages, it was a great buy, I use it once in three days, advise not to use daily.

- Reviewed in the United Kingdom on 23 May 2025Colour Name: WhiteVerified PurchaseI don't think there is big difference in between this type of tens ems machines, but this one equipped with type C charging port and does very big difference. Working very well, one charge last around one week using it every day for 20-30 minutes. Overall looks good quality and works well.
- Reviewed in the United Kingdom on 14 March 2025Colour Name: BlackVerified PurchaseEasy to use and works well definitely blocks the pain when in use. The battery life is good and it’s a good size to pop in your pocket and walk around while using it.
- Reviewed in the United Kingdom on 11 April 2025Colour Name: RedVerified PurchaseAbsolute game changer if you suffer with back issues. Felt total relief after the first use. No back pain after 4 years. Continuous use is needed but it's very comfortable and easy to set up and use. Battery life is amazing and doesn't need charging too often. Don't buy a cheap tens machine as they are rubbish. Spend a few quid more and you will feel the results.
- Reviewed in the United Kingdom on 14 May 2025Colour Name: BlackVerified PurchaseI bought this because I saw the glowing reviews of over 1,000 buyers however when I got the product I was very excited and I set it all up and it was not working it was not working properly some buttons didn't work then I thought maybe I don't know how to use it properly maybe I need to look at the instruction manual a bit better but no, there wasn't anything in there that I was doing incorrectly. Then I went back to site and looked at the other reviews and noticed this issue has been repeated by other buyers on so I'm definitely not the only one so I've returned it and got my money back need to look for another one now.
Complete waste of my time.
