Product Customer Reviews

It's perfect
be careful to read the instructions carefully
GOOD
does the job
Really a bad buy. I had pain in my jaws from the mouthguard for 4 days. Couldn't breathe properly with it, it hurt.
Very painful to wear because it doesn't fit, it's better to spend 10 or 15 euros more to buy a better product.
Perfect
Poor quality. Didn't form properly.
Simple, nothing more to say.
It is difficult to choose the size, and it is impossible to try it on due to personal hygiene, so those in need should think before buying.
GOOD
It's for rugby
this remains a mouth guard, not usable for dental appliances, see rather molding with an ortho dentist
Very cheap quality products
Very comfortable for bruxism I find it very useful
