Input: This guard is Very big and bulky when in your mouth. It’s marketed as a anti snore device, but it doesn’t work for that at all. Snore just as badly as always have; but now can’t close my mouth to sleep while wearing this because it’s huge and uncomfortable 😣

Not a great guard unless you’re built like a sumo wrestler
