ZQuiet Comfort Size #2 is a soft, flexible mandibular advancement mouthpiece that holds the lower jaw about 6mm forward to open the airway during sleep. It is the larger of ZQuiet's two sizes, aimed at people with an underbite or a normal bite and heavy snoring. Its living hinge and open front let you breathe through the mouth, talk and sip water, and it is far less bulky than hard-shell devices. Owners report mixed results: some get quieter nights, but the 2.4-star average reflects frequent complaints about jaw soreness, drooling and fit.

Ratings are low overall. Some owners say it reduced snoring and felt comfortable, but many report jaw pain, drooling and a poor fit, and several say it did little for their snoring.
This is a single ZQuiet Comfort Size #2 anti-snoring mouthpiece, sold as a refill pack. It gives a slightly greater +6mm jaw adjustment. Size #2 is recommended for people with an underbite, or a normal bite with heavy snoring.
The mouthpiece is soft, low-profile and flexible, with a lightweight feel. It is less bulky than similar products with a hard plastic shell. Its living hinge design and open front let you open and close your mouth naturally, talk, or take a sip of water.
Minor side effects such as drooling or jaw discomfort are normal and tend to fade with consistent use. For hygiene and performance, replace the mouthpiece every 4-6 months. New users can start with the 2-Size Starter Pack to find which size works, then order Size #1 or Size #2 separately.
