I've used both boxes and one I bought elsewhere and haven't noticed any difference - that's NINE uses, although they say you will see results after just one use! My teeth aren't even particularly NOT white and definitely not yellow, just downright average - I just thought they needed a bit of whitening. I left a message to customer service # on the box SIX weeks ago and emailed last week but have had no response. Don't waste money.
