Great for old folks, too!
I used this to protect a broken front tooth when I went in for surgery, the anesthesiologist was extremely impressed, he said he'd have refused me as a patient because of the risk of damaging the tooth further. Thank you, my surgery was a success!

By far the best for BJJ training
One of the best fitting and low profile mouthguards I have ever bought. It was surprisingly easy to heat and mold to my teeth/mouth the first time. Awesome design that stays in place really well (you get that satisfying click into place).

My 2nd one of these.
So I’m on number 2 of these mouth guards. Love the face I can still talk with out mouthguard mouth being super bad, breathability is still amazing, borderline no weight, and due to being able to mold it multiple times I can get it to fit my mouth true to size. Being one of the few mouthguards with a ton of moldability if you mess up a bit makes this a great purchase. It’s high quality, I train in Muay Thai and when we hard spar it’s definitely saved my teeth and jaw before. Now, I had to purchase a second one due to me finally biting through (at the time I thought I did) my original one and not taking as good of care as I should of it began to have a bit of a smell to it. Now after I remolded my OG one (and did not bite through it like I thought), cleaning it and remolding it I have 2 of em. The insurance on them is also great. Note - follow all instructions to the letter or watch a video on how to do it. You get 20 times to mold it before it loses its insurance policy and gets weak. It took me 8 times on the first one and only 3 times on this one. This is also great if you have a gag reflex on other guards that aren’t custom ones.

Great First Mouth Guard with Minor Adjustment Period
As my first-ever mouth guard, I was pleasantly surprised by how easy the molding process was. The company provides clear video instructions, and there are plenty of helpful guides online as well. Shaping it to fit my teeth was quick and straightforward. The mouth guard itself is firm and provides excellent protection for the teeth. It’s comfortable to bite on and feels light, which is great during intense boxing training. I had no trouble breathing or focusing while wearing it, and it didn’t interfere with my performance at all. The only downside is that, at first, it puts some pressure on the front upper gums. It took me about 1–2 sessions to get used to it, and even after removing it, I could still feel the pressure for a little while. This might be a normal experience with mouth guards, though. Plus, once you’re sparring and taking punches, you hardly notice it—pain is part of the fun, right? Overall, it’s a solid choice for a first mouth guard. It does its job well and is comfortable after a short adjustment period. Definitely recommend it for beginners!

Great mouth guard for BJJ
I've bought it because a lot of people on YouTube saying that this one is the best mouthguard. And they were right, it fits incredibly great and it makes easier to breathe, talk and drink, and feels like protect really well. So I 100% recommend it, if you are a hobbyist bjj practitioner - this one worth its money. p.s. I re-boiled it 4 or 5 times until it fit really great - and recommend doing it until it fits great, because it is hard to make it fit well from the first time :)

Not worth it.
Once it’s molded and hardened, the mouth guard is super hard and very uncomfortable to wear. The molding process was easy but with how hard the plastic is, I doubt its ability to absorb impact. Not buying again. If you’re spending money on gear that’s important, spend the few extra bucks on a mouth piece. The gloves can wait

Was skeptical at first but now won't buy any other mouth guard
After training you jitsu for some years now I always had the fear of getting my teeth knocked out during a roll. Well I caught a nasty knee and it lead me to buy a mouth guard. The sisu 2.4 is just amazing. Moldable up to 20x although I don't recommend doing that. Super comfortable thin variety of colors to choose from and best yet is their 1 year warranty with up to 35k of dental work obviously with stipulations but it eases the mind to know and have that insurance. The fit is literally like a custom mouth guard from a dentist. Its easy to talk. breathe, and drink with it in. Not uncomfortable at all either you almost forget you have it in. I've been recommending this mouth guard to all my bjj peeps. I'm fairly convinced that ive found the only brand of mouth guard I will ever buy from now on.

Great fit. Rubs inner lip raw
Very easy to breathe out of. Fits and protects well. A little hard to take out due to how well it fits. . Rubs inner lip raw so be wary of that.

Produit vraiment novateur. Le moulage est très simple à réaliser. Le fait que le protège-dents soit livré plat permet de l’adapter facilement à la dentition de l’utilisateur. Utilisé pour du sparring en boxe anglaise, la protection est équivalente à des modèles plus volumineux. Il est très rigide. En revanche en bouche, la matière s’assouplit légèrement et le confort est inégalable que ce soit pour respirer mais aussi boire ou parler. Il se fait complètement oublier. A recommander sans hésiter.

Wish I had found this brand years ago I can’t believe a gum shield could be so thin and strong after years of my daughter refusing to wear one because the others were too thick even ones made by the dentist and she felt like she couldn’t breathe,drink or talk while playing rugby this is a game changer and she has worn this for her last 4 games no complaints and even got her friends to order them very lightweight easy to mould very comfortable but do make sure you research first as there are different ones and size's for different contact games or games like hockey

Riktigt lätt att forma och har inga problem med att ha den i munnen, stör mig inte alls.

主人がジム用に他のものを購入したら 届いてすぐ割れてしまいこちらで再購入 上手く作れたみたいです

All'inizio potrebbe spaventare perché a differenza degli altri paradenti è duro. Comunque offre una buona protezione e in bocca non si sente, si riesce anche a parlare. Per il contatto leggero è fenomenale, per i colpi pesanti invece ancora non l'ho provato.
