OPROInstant Custom-Fit Mouth Guard, Dentist-Level Comfort, Protection & Fit - Moldable Mouthguard for Football, Boxing, Rugby, MMA, Lacrosse, UFC, Ice Hockey Mouth Piece - Includes Mouthguard Case

Follow the instructions and you'll have a perfect fitting mouth guard. I use it for boxing and got cracked hard in the jaw last night and it likely save me from concussion.I have a nasty gag reflex and unit doesn't trigger as much with this as it's not super bulky and doesn't extend too far past my back teeth.Ask yourself do you have a $7-15 brain or a $30 brain? The little bit extra is worth it imo.

The media could not be loaded. I remember looking at some videos and they said that opro is the best mouth piece and after 1 year I can confirm it. Its not bulky so you can talk with it in your mouth, quality is great is a comfy and snug fit, molding always kinda sucks but its good, and as long as you bit down it wont fall out of your mouth.

I bought both the Opero and Venom Challenger mouthgard. And I have to say there is no comparison between the two. The Opero fits my mouth like a glove. The Venom Challenger did not fit as well. Because the Opero comes with the that plastic tray thats used for molding it hugs the teeth and gums for the best fitting when you bite down during the molding process. If the Venom Challenger came with a plastic tray for fitting/molding process I am sure it would be able to compete but it does not.And Opero comes with a one year dental warranty! Because they are that confident. And when I wear their mouth guard I understand why. I am not concerned to get hit in the mouth and when I wear the Operos. I can not say the same thing for the Venom Challengers.I can’t tell you how many reviews I see of people purchasing these $35 Opero mouth guards over $100 mouth gaurds that you have to mail your mold to. These are best.

Bought for my son for lax season. Says it's comfortable and durable

Best mouthpiece I've ever used. I use it for BJJ/MMA both. It fits perfetly in my mouth, stays in, and allows me to breathe so much better then anything else I've tried. This is my second one.

Not sure what type of adult has this small of a mouth but wow this thing is tiny. Im afraid I will swallow this thing during class. Save your money.

The media could not be loaded. These are snug. And feel super comfortable. Follow the instructions and you'll be fine. Don't bite down too hard. Just enough to create firm pressure. Lots of room to be able to talk and move your tongue around.

This is the 5th Opro mouthguard that I have purchased for my family. I have 4 rugby players, 2 of whom are also wrestlers and not one time have I been concerned when they are going to compete about the safety of their teeth.This most recent purchase was for my collegiate level rugby player. He forgot his last one in the pocket of his shorts and I went through the washer and dryer. It was able to be remolded but of course that wasn't good enough. He loves this one and has now used it for his newest sport, boxing.I always recommend Opro to my athletes (I am a rugby coach) and to their parents. Opro is tops in my book.

Tried various shock doctors and underguard boil and bite mouthguards, this is levels above in terms of fit. Really snug fit to the point where you need to actually pull the mouthguard to get it off, and it's thin enough to comfortably breathe and speak. it's been holding up well for a month now with no material coming off, really worth the price.

I bought this mouthguard for my son who plays ice-hockey in the U13 and often with U15 age group where they already play sometimes hard contact.Due to the title “instant” the fitting process was supposed to be on the go but it is technologically the same as other “custom” fit mouth guards have - boil, heat, bite and cool. Neither fast nor instant. Typical marketing manipulation.Moreover, unlike other brands, this one has extra fitting feature - double case which makes the process extremely not convenient especially for the teenage who just physically was not able to place the whole huge fitting construction into the mouth so it went finally to a trash bin.All the rest - the guard looks good and protective… maybe

Paid a bit more than I usually would but was worth it. Fits my son much better and he says it's much more comfortable than his last one. He gives it 2 thumbs up. Was really easy to mold too, following the instructions provided.

Ottimo paradenti che svolge ottimamente la sua funzione

Fits amazing. The best mouthguard money can buy. But could be easier to put on.
