Not a miracle, but does a good job [SEP] I just spent $600 at a local dental office for what I could have done at home with the $199 or less Glo kit. The dentist just did Step 1 of a 6 day whitening process, using the kit! They didn't offer any other "magic" and my teeth looked better, but not what I expected (completely white, Hollywood teeth). Now I have to do it at home for 5 days in a row (they gave me the kit). It is working, but it's a process, not a one and done. I cannot believe this dentist took advantage of me like this. Live and learn. Thing I do not like is that the gel or bleaching tubes are very hard to use and you end up wasting about a third of the gel because you cannot press it out. I think the people at glo know this. A much better application would be in syringes.
