Will you buy this again? Hell No.
Straight garbage. Not only is this product not as effective as I had expected, but it also makes your teeth sensitive when you brush. The part that angered me the most was that it's very difficult to get the contents out of the bulletproof container. They could have put this gel in a toothpaste-like tube, but instead they put it in this ridiculous bottle where it's real difficult to get the gel out. I threw mine out when I still had some in it, I got tired of fighting the bottle. This is probably how they sell more of it.<br /><br />Edit: Since I last posted my comment, Arm and Hammer took my advice/recommendation and repackaged this product in a tube-like package, like I said they should've done. So it's good that they adopted my suggestion and the suggestions of those who advocated this. To all of those who've purchased this product, you're welcome.
