Not that impressed
Its an easy and straight to the point product. This is my second time purchasing. I purchased my first from the dentist. He told me use only 30min, so that is what I did, until the prescription ran out. I noticed nothing but slight discoloration on each tooth and a bit of sensation for a minute. I went to amazon and read reviews on it and seen some people did follow the directions and did 2-4 hours and had better results. So I purchased again in hopes of seeing better results with a longer duration. Four hours is what I did. As I took them off, I felt sensation and seen a little results but not all the way around. SMH, I guess I’ll try again.
