Question: 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 😣

Answer: Not a great guard unless you're built like a sumo wrestler

Question: The sizing chart was so far off it is not even funny. These would not even fit over my thighs. Had to give them to my son. Very dissappointed in this

Question: Amazon is great with their refund policy. I never could get this bell button to pair with my chime even though they are from the same company and the description assured me it would work with any Zenith chime set. Wrong. Thank goodness for Amazon and their amazing customer service. Many thanks. For now, anyone wanting entry will just have to use the 5 knuckle method and knock!

Answer:
Never could get it to work with my Zenith door chime.
