DO NOT WASTE YOUR M9NEY!
Do not waste your money like I did.  I don't know why I didn't check the reviews before I purchased, but I didn't.  What a mistake.  The first thing I noticed was that the product was a much lighter purple than other V34s advertised.  Fine if it worked, but....  check out my before and after pictures.  I think the before picture was whiter.  Now, it does say this is a POST-WHITENING treatment, so I suppose after you spend the money and time to<br />ACTUALLY whiten your teeth this could possibly help with any residual yellow stains.  But it begs the question of what exactly this product is supposed to do.  There are no instructions that say it takes x number of uses to see results.  I'd say this is a bogus product.  On the plus side it tasted good.
