Hate to say but it was not good at all
I got excited by a tv commericial for this product so much so that I went straight to Amazon and ordered it BUT didn't read the reviews, shame on me.  I just don't see much difference and I so wanted it to work.  My teeth are not stained just the yellow from coffee drinking.  I think that because you have to apply the product tooth by tooh and rub with the included 'swab' for a bit per the instructions, the teeth get 'cleaner' and shinier, BUT NOT WHITER!<br />Don't waste your money.
