OPRO Instant Custom-Fit Mouth Guard – Dentist-Grade Comfort – Moldable Sports Mouthpiece for Boxing, Wrestling, MMA, Lacrosse & UFC – Impact-Resistant Gum Shield with Case – (Black/White, Adult)

Followed the instructions exactly the way it said and it’s the best fitting mouthguard I’ve ever had for MMA and BJJ. Fits perfect and I can’t remove it without my hands. Plus it doesn’t give you the gag reflex. Tried to remove it without my hands by just pushing with my lips and tongue but it’s stuck in there.

Pretty good. This is my 3rd one. I love how these stay in place during grappling, kick boxing, boxing, sparring ect.

Got the mouth pc last second for a mma fight had coming up. Used it and it honestly worked not as good as expected. I felt like it wasn't as large as others I have had and in general covered less of my teeth. I had some cuts on my gums and in my mouth after the fight. What I do like about it however is the colors and how I was able to reboil for a better fit. Good mouth guard but not for competition.

Don't have any pictures right now but it offers wonderful protection, the thickness and moldability married with the ease of use and ease of application makes the functionality of this mouthguard stellar. You can tell that it's made with love and that it is built to last to give your little fighter a comfortable feel where they can still breathe when they need their mouth open and not breathing through their nose I would definitely recommend this brand and any style that you happen to choose, I don't feel like you're going to go wrong

Good quality

The listing is not clear, but this is not for individuals with braces. The packaging does have this in very small font. Unfortunately we did not notice this until after we attempted to fit. We contacted the seller, but they have said there is nothing that they would do.

I got tired of off the shelf mouth guards constantly falling out during kickboxing class. I started looking into getting a fitted dental mouth guard and was ready to spend the ridiculous $120-$150 to have one made. While searching for reviews on dental mouth guards, I came across OPRO instant custom fit mouth guards. The reviews seemed promising as a possible option to try. So, after a bit of pondering I figured I’d give one a try before dumping over a $100 on a dental mouth guard. The forming process was pretty much the same as any other mouth guard, but the addition of the dual form tool made forming easier and provided a tight fit. The mouth guard basically clicks in place and stays put. It takes a little force to pop it back out, which is exactly what I was looking for. The mouth guard in the forming tool is a bit bulky, so it’s a bit awkward to get in and out of your mouth. It’s taller and thicker than the standard run of the mill mouth guards, so it covers more area and provides better protection. I am very pleased so far with this mouth guard, so I ordered another for a backup spare. If someone is looking for a great custom fit mouth guard for MMA, kickboxing or other contact sports without dumping a small fortune on a dental mouth guard, OPTO instant custom fit mouth guards are a great bang for the buck option.

I’ve been training in martial arts for 23 years and have been teaching for 15 years so honest opinion of the OPRO Mouth Piece. This has great cushioning to protect the jaw and teeth on impact from medium to hard contact to jaw and chin. If you’re looking for more cushion protection and impact absorbing mouth guard this is a good fit. My own experience of training comes from Boxing, American Kickboxing, Muay Thai, Wrestling, Taekwondo, Krav Maga and various forms of Fire Arms training (Shooting to Pressure Testing scenarios with Simunation Rounds). So, the impact to jaw or chin can vary for each of those systems based on what the drill or session is. For me personally I also like when the mouth guard can clip onto my upper teeth such as a custom dentist mouth guard or Shock Doctor Trash Talker. That being said I use different mouth pieces depending on what I am doing. When training students I typically use the Shock Doctor Trash Talker Mouth Piece since it has slimmer profile, clips right on to my upper teeth and I can speak clearly to my students without it falling out, or when grappling in class or in a firearms hand to hand combatives course. Since I’m not so worried that students will land any shots on my head area due to level of ability compared to mine or don’t have to worry about it falling out while rolling with another guy retaining my training firearm or attempting to take the other guy’s training firearm. However, when competing or training with competitors/Instructors at my level in a striking discipline such as Muay Thai, Kickboxing or MMA, I use my dentist mouth guard or when traveling I’ll be using this OPRO mouth guard as a back up. Since it offers more cushion protection from head strikes that can happen when training or competing with others at my level of ability. Overall not mind blown from this mouth guard but not dissatisfied from it. Will give it a few sparring and grappling rounds to see how it holds up and keeps up with what I do. If anything it’s going to be a back up mouth guard. Since I always recommend to students and professionals to have 2-3 mouth guards when traveling or training at your home academy. And depending on the amount of use you put them through, change them out every 6-12 months or so.
