mouth guard

the size is not adapted to the recommendations, but correct product


Super clear instructions and if you do it as it says, it works like a glove, I recommend purchasing.

Fragile product

From the first use, the transparent part separated from the black one. I only did light sparing, the lower transparent part ended up in pieces, shredded by my teeth! The plastic is cut, and where it isn't there are deep indentations from my teeth. Nice little pieces of plastic in your mouth! We expect more quality for the price. For comparison, I had been using Decathlon's basic transparent mouthguard for several years. He held on and did the job for 4 years. I can't say the same about this one. To avoid. I'm going to have to buy one again, this time I'll take another brand.

The mouthguard fits very loosely (it should sit tightly and “stick” to the upper jaw when the mouth is open) in the mouth. I've tried adjusting it several times, but it just doesn't work. A good mouthguard is not loose and sticks properly. Can the face mask be returned, refunded or similar?

Not terrible

The most comfortable gaiter I've ever tried! It molds very well to the teeth, is thick enough and protects the oral cavity well. I recommend!

very disapointed

Bought for my son who is a goalkeeper to protect his braces. No specific “football” mouthguard, so after having seen it with a saleswoman in the rugby and boxing departments, we left with this mouthguard, identical in fact to the one sold for rugby. Is sold for 170cm and over, it is also too big for my 16 year old son measuring 182cm! Test once in a match, he quickly leaves it aside because it hinders him rather than protects him!

suitable for use…

suitable for moderate use for beginners. wears out quite quickly and you end up with pieces of rubber in your mouth due to the friction of your teeth.
