Probably the best mouthgaurd you can buy without going custom. Good fit and great protection

I started boxing and with all of the other stuff I needed getting a dentist fitted mouthguard wasn’t in the budget. I read a lot of reviews and gave this one a shot. If you follow the directions you will get something right at or a notch below dentist fitted. Pro’s: using the kit I was able to get a mouth guard that I have to pull out with my fingers. It will not come out on its own. I’ve been punched in the mouth a few times and didn’t feel anything as far as my teeth are concerned. The directions were straight forward and the mouthguard fits great. Only took one boxing session to get it to the point where it was comfortable and unnoticeable to wear. Cons: there was a sharp corner on the inside upper of my mouth. I was able to gently sand it with a dremel tool and make it disappear. I would consider that finish work and something that may need to be done with any mouthguard. It was uncomfortable the first time I wore it, but after that it’s been something I don’t even notice once it’s in place. Conclusion and notes: one thing I did when it was molding in my mouth is to push inwards onto the mouth guard and assist the tray system in applying pressure inwards to get a precision fit. I haven’t don’t this without that technique, so I can’t say if that aided in the tight fit I got or if it made no difference. It was actually such a tight fit at first I thought it was stuck in my mouth until I figured out which direction to pull to remove it. After using this a couple times, I’ve scrapped future plans of getting a dentist fitted mouthguard and will be buying another of these when the time comes. If you don’t chew on your mouth guards, I’d expect this to last a year or more.

Very good

I want so badly to love this mouth guard. The unique boil and bite tray is great in theory but I’ve now gotten 2 of these, followed the directions to a tee and ended up with an uncomfortable end fit that’s still not perfectly molded to my teeth but so tight that those imperfections are really noticeable and uncomfortable. With a regular boil and bite, the fit isn’t perfect but there’s enough space that you can get a fit that won’t come out on its own but still is comfortable. These OPRO guards are too tight fitting to be forgiving of those tiny imperfections and without a true mold of your teeth, there’s no way to get that perfect fit reliably. You also only get one try at it, other boil and bite guards can be re boiled and adjusted but these are a one shot thing, a second boil will ruin it. Lastly the edges, particularly around the center line are rough, this guard is for jiu jitsu where my lips get smashed into the guard often and those rough edges feel sharp just wearing it. I’m not confident enough in it to wear it for its intended purpose. I thought maybe the first time I just made a mistake somewhere along the way but the second attempt didn’t head any better results. If I had it to do over again, I’d either stick with a standard boil and bite or I’d spend the money to have a real custom guard made. I wouldn’t recommend these as a good option, the mix between custom like tightness and the imperfect nature of a boil and bite fit isn’t a good combination.

It's a really nice mouth gaurd, but I did mess mine up a bit, and was not aware to let it sit over night to fully mold and harden back up, so now It's a little lose on the front teeth

After getting kneed in the teeth and wearing the 3D printed Kevlar mouthpiece, which I found out was trash, I decided to try another mouthpiece, opro is the best, great value and feels great in your mouth/on your teeth.

I bought this mouth guard for jiu-jitsu after reading the good reviews. I dont like the fit at all and had my lip completely busted tonight. The guard is very deep and when it molds to the teeth, it rides up the gum. Its also fairly think, so it causes my top lip to stick out a bit. With most mouth guards this isn't an issue, but this one has a softer inner piece to mold to teeth and a harder plastic shell that my lip was smashed against during sparing.

Only had one mouthguard prior to this, but this feels like another world. I can speak clearly with this on and it feels great. Tight fitting. It's a great mouthguard and fairly low profile, so it's not making my jaw any bigger than it has to be

The mouth guard is easy to mold and fit. It fits really well!

Ottimo paradenti, si modella perfettamente e rimane bene in posizione. Non paragonabile per qualità ed efficacia a modelli da 10 euro

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.

Best mouthguard that I've tried in all 5 years of training boxing. I made it twice because the first one didn't fit like I liked to and there was really no problem at all doing all the process again.

Easy to fit, easy to follow instructions. Fits nicely. Only issue I had is I brought it to help me stop grinding my teeth while sleeping, it is a bit too bulky to sleep in
