Not for Larger jaws!
Just got it yesterday, Jury's out on cleaning & whitening till i have a chance to put some cycles on it.<br /><br />One thing stood out however, the "U" shaped silicone part your teeth fit into is designed for medium / small jaws, I'm a "FatHead ;-)"  and as such have a larger jaw which the silicone part does not extend all the way to the back molars.<br /><br />Stay Tuned & I will update "Overall" rating when testing has been completed.
Rating: 3 stars
