I bought a couple of them off Amazon several years ago. The first one I stopped using after a few nights as the kibble felt like it was cutting the insides of my mouth. The next one, I've used for 2 years. Immediately felt the benefits of having a good sleep at night. Friends that I often travel and bunk with tell me my snoring is much more reduced. I could sleep on my back without choking!
I stopped after 2 years because I noticed my front lower teeth no longer align with my upper teeth. I can't use my front teeth to 'saw' off food anymore. I always woke up with a really sore jaw and lots of pain around my teeth. The lower teeth always felt like it was bent forward when I woke up.
Lately, I've been considering getting another pair, because I think the one I used was meant to be swapped out every 6 months, which I obviously didn't do.
