but my issue is that there is this double-side tape that you have to apply every morning to get it to stick to your back, and some days it takes time to scrape off the prior day's tape so the new tape will stick. So it's just a bit of a hassle getting it on every day.
But once it's on it's pretty awesome and I found it helped me a lot. You can adjust the settings so it doesn't buzz you too often. On the most sensitive settings, if you just bend down to pick something up off the ground you get a buzz.
