5.0 out of 5 starsWorks as intended, satisfied with the product!
Reviewed in Canada on December 16, 2022
As a first time buyer and operator of a TENS machine, I am confident to say that this product works as it was intended. I purchased it to provide temporary relief from a work injury for bilateral lateral epicondylitis (aka tennis elbow) on top of physiotherapy, chiropractor, RMT, and other recovery exercises. Delivery was quick with prime (next day shipping) and everything was nicely packed in a small box. I had some technical issues with one pad not working by itself in port "A1", but then I realize it needed two pads to work (same for port A2, B1, and B2). It's like how electrical current travels from the negative (-) lead to positive (+) lead and using one pad won't do anything or in other words you won't feel anything. I tested it on both my left and right shoulders, left and right arm/elbows, and felt a tingly, vibrating, or sometimes jumpy feeling (depending on the mode and intensity level) however it was very satisfying after a 20 minute session (note: the unit starts when you increase the intensity level from 0). I wouldn't operate it longer than 20 minutes per side, but there is an option to increase the time (up to 60 minutes max).
The design of the machine is impressively light and the size is about as big as an iPhone 5c. The micro-USB charging port might be off-putting for some buyers as everything should be switching to USB Type-C, but that didn't bother me. I only had the unit for 2 days with no issues, but will provide an update if something changes.
Note:
I found out from this merchant's support team that they are a new seller on Amazon and kudos to them for providing me a quick reply (same day response) regarding the issue to register the product for extend warranty (3 years). According to their reply, their website process was not finished so my warranty was manually activated and I was also asked to provide my shipping address to receive the free gift as part of the warranty registration.
