Review (5/5): Guaranteed Whiter Teeth!
The GLO system is simply amazing. I had used the vials years ago but had never tried used the device, but I’m glad I made this purchase. After one use, my teeth were noticeably whiter. And the best part? No sensitivity. If you’re afraid to make this purchase of the price tag, pull the gun. This is one of the best systems on the market. Very happy and will definitely be purchasing vials again in the future.
