Until now had several mouthguards, usually made of plastic. The gel plastic variant was easiest to adapt (no burning of the gums) and sits best in sports (boxing). Customize had the mouthguard about 3x before I attempt it there, but this has still friction and above all easier than with plastic versions works.
One drawback is the plastic skeleton is that sharp at the edges. This should be completed after the annual adjustment with sandpaper to prevent injury. Therefore, a point deduction.
Am satisfied and the same product would buy again.
