Review title: Not all its cracked up to be
Product review: It whitened my teeth a little but not to the extent advertised. And it was very messy! You have to leave the trays on for an hour, so if you want to do it make sure you have no one you need to talk to and that the phones are off the hook. Its very inconvient and it sortof irritated my gums. Also its very foamy, so like I said, messy. Goodluck
