SleepProNightGuard 3mm Hard Soft Bruxism and Teeth Grinding Mouthpiece Gum Shield

First off the description of hard/soft material is a bit vague. It's a soft plastic. I was hoping for hard plastic, but ok whatever. Next, as they sent the item it would have caused damage to my gumline as it the execution was sloppy and the plastic rubs the gums. It should have been molded then sanded back. Luckily I have a small sander and did this myself. My sander isn't fine enough though and leaves the edges a bit raw, so it's not the most comfortable guard I've owned. Overall, I wouldn't buy this again and would not recommend anyone else to waste their money.
