Review: Wasted my money - This product didn't live up to expectations. I followed their instructions twice, but couldn't get my teeth moulded. As a result, it slipped in my mouth and was totally unusable and didn't want to choke on it. I put it in the bin 30 minutes later.
Review: Useless - It does not work as described. It does not fit, it does not match. The protective form prevents you from making a normal cast, because of what the whole product is simply useless, money thrown away.

## Questions & Answers

**Q: I have a small mouth. Does this fit well with small mouthes? If its too big,can it be returned?**
A: It has a tray that you bend to the shape of your mouth. Follow instructions to a tee and you'll be fine. I however experienced soreness while trying to mitigate TMJ so I stopped using it and learned to sleep with my mouth relaxed. As far as a return policy im pretty sure there isn't one.

**Q: Does this work good? Is it comfortable for a smaller mouth?**
A: I have a smaller mouth and it works well.

**Q: Can you wear this with braces?**
A: Yes, it sits on top of the teeth and would not interfere with braces.

**Q: Will this make me drool?**
A: I've been using this for about 4 months and it does not make me drool
