I tried them and they really do work... was worth the money

besides if u look on amazon and other places it says
Money-Back Guarantee:
Use all of the upper strips first. If your teeth are not noticeably whiter, return all the lower strips for a full refund. See Package Insert for full details.

After doing the upper teeth I didn't return them because it was noticeably whiter

..the trays cost me $500, but they worked
