It has shown a little improvement of my teeth colour, so it is worth using until the end. I would say that it is probably the best teeth whitener I have used so far, so I am not sorry I purchased it and would give it a go if anyone would like to try it as I'm not negative on the product! Product arrived very quickly - thank you!

Used this as instructed for two weeks and saw absolutely NO change in whiteness, not even slightly. Took before and after photos. Would not buy again.
