Review (2/5): not worth the money to me
i only got one shade brighter. went to my dentist, and did 5 days so far now at home in addition to the glo at the dentist. I am only one shade brighter. I wanted WHITE teeth. My fiance who used some other bleaching kit at the dentist has disney white teeth... that's what i wanted for all the money i paid at the dentist and for the kit. My teeth being one shade whiter (even with avoiding coffee and wine) is not worth the $400+ i spent at the dentist and with this kit. Dissatisfied.
You can decide for yourself if that's worth the money to you or not, however. To me: not so much.
