The short version: Don’t be deceived by its small appearance! The Venum Challenger Mouthguard marked adult/11+ IS THE CORRECT SIZE! The longer version: Initially I also thought I got the wrong size, and started a return ticket. After googling it I found a very helpful comment on the .com Amazon site. You can find the whole review here (scroll down to Tiffany): https://www.amazon.com/Venum-Challenger-Mouthguard/product-reviews/B075TDCS2D To really be sure I also asked the manufacturer. This is what Venum US wrote to me: “We only have 2 sizes for the mouthguards. The one you got is for adults. The other size is for kids which is for 10 and below. And yes, our mouthguards are small compared to the usual size. They are built that way, designed to be more breathable.” Using the instructions that came with the Venum mouthguard, and the tips from Tiffany’s post (to not bite too firmly), it fits perfectly. Conclusion: Despite the size looks completely off on first appearance, as long as the box says “Adult” and/or “11+” the mouthguard IS THE CORRECT SIZE - I.e. suitable for Adults and children near or in their teens. The Venum Challenger IS DESIGNED TO BE SMALLER than standard mouthguards to FACILITATE BREATHING, in addition to its shock absorbing functionality. More oxygen - better performance. Read more

Have found that this product suits well for grappling, does not feel too bulky in the mouth at all. Read more

J'ai récemment acheté le protège-dent Venum Challenger et je suis très satisfait de mon choix. Il se moule facilement à la forme de ma bouche, offrant un confort optimal pendant l'entraînement. La protection est excellente, ce qui me permet de me concentrer sur mes performances sans craindre pour mes dents. De plus, il est léger et ne gêne pas la respiration, ce qui est un atout lors des séances intensives. Et s'il est bien moulé, tient bien en place et reste accroché. Ce qui permet de "parler" En résumé, c'est un protège-dent de qualité qui répond parfaitement aux besoins des boxeurs. Je le recommande vivement à tous ceux qui pratiquent la boxe ou d'autres sports de contact ! Read more

These are a must-have! My son does jiu jitsu and must have a mouth guard when they “go live”. Easy to mold, can be remolded if you get it wrong, comfortable. My son was 11 when we started using these. He’s a chewer, he’ll chew on it when they aren’t rolling and will mindlessly chew so these last him about 6 months and then I have to get a new one. He’s 13, almost 14 and doesn’t chew them as bad now so they las a long time. Love the different color options. Recommend! Read more

I found the instructions easy to follow, and it was a straight-forward process to mould the mouthguard. The mouthguard is much thinner than the one I was using, which makes a huge difference with my breathing. Read more

It looked good and the quality is good and before molding I read some reviews and videos and was told not to bite too hard otherwise all the gel comes off and I bit as light as I could while sucking yet the gel still came off and it would not stick to my teeth well after the full process. Pls be more careful and bite down really light they should definitely make it more clear in the instructions. Read more
