Customer Reviews of Crest Whitestrips Pro Effects,10-Day Dental Whitening Formula System, 40 Strips (Packaging May Vary)Customer Review: Ineffective and Painful
Does not work. Very little results. Also, excessive pain caused me to use them once a day after 4 days of using them twice a day. Let's see if they keep their word about a money back guarantee when I contact them. |
