After extensive research, I bought this premium tens unit. Unfortunately, it only works some of the time. The wireless concept sounds interesting, but in my opinion, adds complexity since sometimes the units don’t pair properly and the device does not turn on. Pads proprietary, expensive and wear out quickly. As others mention, the app does not add any actual diagnostic value and is nothing more than an app based version of the instruction manual. it provides no customization whatsoever.

This “app” does nothing more than display the Chirp website - including the large banner telling you to download the app for the “best experience.” So the app experience is actually worse, since the main benefit it could provide is not having to close out of a box that takes up 20% of the screen and which you have to do every time you open the app.

Like other reviews mentioned, this only displays the website in mobile view. It doesn’t even show how to use or place all the pad types, just limited info for the trigger point pads.I do like that there is some reference about where one is experiencing pain and where to place the trigger point pads to hopefully alleviate the pain with their use.Should have more info about how to use and place pads.

I just purchased this device from my surgeon’s office. I debated as I have access to a wired version of NMES, but was drawn in by the wireless technology. It is challenging to get a comfortable enough amount of stimulation to produce a muscle contraction. An optimal configuration for this device would allow for dialing in the pulse frequency and width to customize the stimulation. I need to play more with this thing but my first impression is that I just wasted my money.
