Very good

Great product.

Fit perfectly, could breathe and talk unlike any other guard

This thing is incredible. It’s actually comfortable and easy to form around your teeth. 5/5 💪

I bought it for jiu jitsu. I'm still able to talk with my training partner, and it fits tight enough where it doesn't fall out or anything.

I play roller derby and this guard is absolutely perfect for it! I can drink and talk with it in which is awesome, and its not super bulky!

My new ace shield is very well made. It is simple to put on and take off. The fit is excellent and simple to adjust with the draw cord. The shield is perfectly sized and attaches quickly and securely to the head piece. I highly recommend it to anyone.

I havent received my package yet as to the post office lost it. But I can say that this company is so great to their customers. I would like to thank Terry for helping me resolve my issue with my order. They definitely put their customers first. Thanks to Terry I will be receiving my package in a few days. I definitely recommend this company.

We love SISU mouthguard and have been using them for years as they are the only mouth guard that does not get pushed out during play and chewed on. My daughter has to use her hand to remove it so much safer. The only reason this is not a five star review is after trying all 3 sizes we still have trouble getting a truly comfortable fit above the front teeth it always seems to curve in too tightly or get a weird fold.

It took a few tries to get it fit right, but now my son wears it and is able to forget its even there! This is huge because with others he would end up spending time thinking about and fidgeting with the mouth guard and losing focus on the game. It’s also nice that it doesn’t have to be taken out to talk or drink so I don’t have to worry about the germs involved in that!

Great product. Exceptional customer service.

Easy to order and were quickly delivered to my home. Shields are comfortable and protective.

It was a bit harder to shape than I expected but we have been happy with it so far.

So far so good.

Fits great

My guard is the SISU Go model. Very comfortable for cycling. Would prefer a clear color, but not an option, so 4 1/2 stars.

I see lots of fellow hockey players with mouthguards attached to their helmets or otherwise held perpendicular to their teeth while they sit on the bench. I put my SISU mouthguard onto my upper teeth in the locker room, and I don’t have to think about it until after the game. And, when I fall flat on the back of my head on the ice (yes, occasionally), I feel almost no pain. BTW, I tried the lite version and then the full version, and there is a difference for me. I get the protection I need from the full version.

This mouth guard fits great. It has such a slim profile in your mouth that you hardly know it's there. Just like advertised you can comfortably talk and drink water with it in your mouth. The mouth guard does not slip or fall out during activities. Couldn't ask for a better product.

My kids both love their new mouthguards. There is a bit of a learning curve in getting the fit correct but it is so worth it!

I love the concept of this mouthguard. I think if we were able to fit it correctly my hockey player would love it. We watched and watched and watched all the videos we could find on proper fitting and never got it to mold correctly. We’ve used all the remolds and more. At this point it’s not going to mold to fit. Kind of bummed!
