Bests & Worsts Reviews from Amazon

They worked great for me - completely solved my snoring problem. I didn’t buy the trial pack, I just guessed at the medium size and they got fine. It does take a little while to get the hang of inserting them comfortably but once you do you won’t really feel them - they didn’t interfere with my sleep at all. My main complaint is that they do NOT last for 10 uses each as advertised. Once I wear one for 3-4 nights (5 max) the device seems to stretch such that it no longer stays in place and will fall out while I’m sleeping. Something to consider in terms of cost if you plan to use nightly.
