SISUMouth Guard Aero - Snow White - Ultra Slim Gumshield for Adults & Kids - Custom Fit Rugby Gum Shield- A Remouldable Sports Mouthguard for Boxing, MMA, Hockey - (Medium 5' - 6' Tall)

took me 6 attempts to mould this right, but now I've got it, its amazing.I bought a regular mouth guard previously, but during the moulding process it made all my upper gums bleed (it was too big for my mouth and was so bulky) on top of the pain from my gums bleeding, the sensory nightmare of the thick bulky thing in my mouth causing all sorts of difficulties (I'm autistic).So i bought this sisu one in hope it would work, and it does! Sisu is AMAZING, its lightweight, slim and painless....if you're autistic get this over the traditional guards....yes its fiddlier to mould, but once you've got it right, its amazing

Great product, I am sparring a lot and because I had invisaling I need to reshape them every two weeks and they work beautifully, it is amazing to see how they reshape when putting in boiling water.

This is a great mouthguard, easy to mould. Doesn’t really feel like you are wearing a mouthguard as it feels like & you can still talk. Was worried it was too thin however I have taken one hard hit with it in place & my teeth are all still a-ok!

Really easy to use and great for roller derby. Haven’t had any falls on my face yet (fingers crossed!) but I’m sure it will protect me if and when this happens...Lost a star due to the packaging being plastic which is bad for the environment.

Easy to use . Easy to breathe. Easy to drink . Easy to talk. Would recommend.

The mouth guard hasn't been cut out of the mold correctly as it has production error where its been 'cut' out, leaving a rough point which therefore causes it to be uncomfy.Yes its light weight and the ventilation seems to help with saliva flow although I dont believe it would actually offer much protect, combined with the fact it's not as comfy as a regular mouth guard I wont be using this product.

I bought this for my 9 year old daughter for hockey, after having tried a couple of other home-fit mouth guards that were making her gag. After reading the reviews, i went for the adult one and I’m glad I did because it really does shrink. It comes as a thin boomerang shape disk which softens in hot water so you can mould it to the teeth. The front is really easy to mould, but the back stayed kind of flat which has helped with the gagging as the other makes are very thick at the back. It fits very well and stays put whereas the regular type of mouth guards fall away when the mouth is open. They’ve definitely got it right with this mouth guard, I’m so pleased I bought it.

Received this item on time as expected although when I have opened the packaging I have realised that this has already been in someone else’s mouth with bite marks and other small marks presumably food or blood. This comes as a surprise for a higher priced item. Poor quality assurance to allow this item to be sent out. I have opted for an exchange as I am hoping this is a one off.
