Cumbersome To Use, Much Worse Than the Old Trays and Gel
Beware before you go for this supposedly high-tech tooth whitener. It's the same thing as using trays and gel, except you have to GET  UP 4 TIMES AND REPAINT THE GEL on your teeth per session! Yep, every 8 minutes, you have to get up an re-apply the gel, and run the unit for another 8 minutes! FOUR TIMES IN A ROW! It's really a hassle.<br /><br />At least with my whitening trays, I put the gel in ONE TIME, and keep it in the mouth for 30 mins and you're done. By the time you're done futzing with this thing, you've wasted an entire hour!<br /><br />Going back to my trusty whitening trays and gel. You have been warned.
