“I’ve used these for several years with it actually replacing my CPAP machine. They work well when you follow the instructions and last for several months. I like to buy a few of at a time.”
“PureSleep's "boil & bite" has worked great for me for 10 years. Gets the job of keeping my airways open at night done while I'm asleep. It's comfortable; conforms to the shape of my bite, is strong enough to withstand my tendency to "grind" my teeth at night, and heavy enough to prevent my accidentally inhaling it. I replace it every 6-12 months as my bite changes, or if it seems to be hardening, or is discoloring.”
