Q: 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 😣

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

Q: The description is misleading. It says it keeps the tank at 78 degrees. If you read the fine print it lists a range between 76 and 80. It only heats my 1.5 gallon tank between 76 and 77 which is not my preferred temp for Betta.

A:
Fine print: keeps tank between 76 and 80 degree. That's a 5 degree range!
