Gold Level Mouthguard, Sports Mouth Guard in Adult Sizes, Revolutionary Fitting Tech for All Contact Sports - Opro by Marcy - Multiple Colors (Black, Adult)

I follow the instructions and the fit was great. There is a moulding cage to help keep pressure. It is somewhat uncomfortable, but the cage gave it a great fit. The guard holds in place really well and you have to really pull on it to displace it.

This is a good quality mouthguard. I followed the sizing guideline and got the adult size for my 11 year old son and it fit his mouth. Also followed the instructions carefully for the imprints. He felt it was too hot in his mouth at first so he blew on it a bit and then was able to hold in for the recommended 30-60 seconds. When we removed it unfortunately he took it out wrong and it smooshed the imprints. Not sure it’s usable for hockey.

While I didn't use the "cage" they include during the forming process, as it didn't feel right in my mouth, the fit still turned out good and the mouthguard stays in place really well during sparring. I wish the rubber was just slightly softer, but overall I'm happy with it.

it works just wasn't that comfortable

The Mouth guard provides excellent protection and the fit is okay, especially with its easy-to-use fitting technology. It feels secure during my football games, which gives me confidence on the field. However, it's a bit uncomfortable to wear for long periods. Overall, it's a good choice for anyone needing reliable mouth protection, but could use a little more comfort.

This sports mouth guard comes with a case, a attachment "leash" - for things such as helmets, easy to follow instructions and the mouth guard itself. The mouth guard is super easy and quick to mold to your teeth. Once molded, it ready to be used and abused - without worry and it's very comfortable to wear. These can even be used as a night/sleeping teeth guard - to prevent grinding, etc.

This mouthguard is comfortable to wear, not too bulky, easy to clean. The quality seems to be decent and it's great for beginners.

Be sure to follow the instructions and don't put it in the same metal pot that you boiled the water in. I did that and it stuck to the bottom ruining the mouth piece. Ordered another one and it came out perfect when I use a different container.
