OPROSnap-Fit Instant Level Mouth Guard – Quick Protection Mouthguard for Lacrosse, jiu Jitsu, Rugby, MMA, Boxing, Wrestling, and Football Mouthpiece – Includes Mouth Guard Case (Adult and Kids)

It says 'No Boiling' but I had to boil mine. When I originally tried it on, the outside hurt the outside line of my gums. Once I boiled it, felt perfect. Easy to breathe and drink with it. Wore it to jiu jitsu training on the same night and actually forgot I had it in, it was that comfortable. Very sturdy as well, even after the boiling. It did not shrink much either after boiling. Highly recommend.

This is the perfect product for me. Just got mine yesterday. My teeth have shifted in the last few years so it didn't fit quite right. I popped it in the boiling water for just a few seconds and now I forget I'm wearing it. It sort of warms with the temperature of your mouth (like real leather on your skin) and fits a little bit better each time. I would recommend this ten times over.

Bought an adult size and it too small for my son who's only 12 years old. Very small and flimsy looking.

I loved that this fit securely without warming it up first. My son doesn't like the fit though. Out of the three mouth guards I purchased with this order, this was his least favorite. He said he felt like it pinched. I'm going to keep it though and try it as he grows. It may fit better when his mount is a little bigger.

It's a good lil mouth guard that gets the job done. I had to follow the instructions to adjust mine for a more comfortable fit, but it was super easy and fits great now! Good price too!

The first thing I noticed was that it looked awfully small. I looked to see that I didn't order a kid's size by mistake, however, the package says "Adult". So i took it out and put it on and immediately noticed a few things:1. It's definitely too small. It only reached to my first set of molars. Hey, OPRO, what about the rest of my teeth? I took it out, rinsed it out and asked my 10 yr old son to try it on. It barely fit his mouth. This adult sized mouthguard may be better fit for a 5 yr old.2. Not only was it small, but it was uncomfortable, especially on my gums.3. Even if this mouthguard was actually big enough for my mouth, there is no way this loosey-goosey generic fit mouthguard would protect my teeth with a direct hit to my jaw. I would definitely use a boil type to soften it up and go for a custom fit.Summary: I should have just gone with what I know and bought another cheapo Sanabul or bought any number of the boil and bite mouthguards available on Amazon. Thankfully Amazon has a great customer service policy and returns were easy.

We bought this mouthguard for my six year old daughter for taekwondo. She is a typical six year old and can’t remember where she puts anything and since she is old enough and a high enough rank to spar, misplacing a mouth guard is a problem. She lost her guard and we needed to buy a new one in the pro shop which is expensive so I ordered this one as well since we don’t have to size it and it is pink, my daughters favorite color. Always a good idea to have a back up. She finds this guard comfortable, which is saying something, she has a pretty severe cross bite (yeah, we have been saving for braces since she was a year because it was super obvious then and her dentist agrees, so something comfortable isn’t guaranteed). Anyway, seems to keep her safe (granted six year olds don’t hit or kick super hard but she’s been okay sparring so far) and it’s comfortable and a color she is happy with.

My teenager has somewhat mobile upper front teeth and finds it very difficult to “custom” mold other mouth guards that require boiling and biting. This mouthguard has protected quite well even with a direct hit to the face. It’s comfortable and stays in place.

Fitted my 12 year old son well, comes in a reusable case, washes well, does the job

Perfect for the kids

Not the biggest fan of this product. I purchased the adult size (even though I’m a petite person) and I still find it way too small even after I boiled it.

Gum shield looks small when it comes. However it fits perfectly in the mouth and installation is quick and easy. The mint flavour in it has a great taste and would definitely recommend. I have bought this gum shield on two occasions and it is amazing and perfect for its use. Defiantly worth its price!

Good enough spare for the price. Not as good as a $30 dollar one, but it didn't cost near as much. You don't need to, but you can, and probably will form it in hot water to improve fit. Now my kid won't get kicked off the rugby pitch when he forgets his nicer gumshield
