Good idea but poorly executed vials
The little vials of the whitening agent are very poorly designed - I had one that was leaking, and one that the brush portion was stuck in the lid so it couldn't be used (there was just a little "pipe" in the "goo" part). The remaining ones worked but it's very hard to get all of the "goo" out so you end up wasting it - think of a toothpaste tube which was solid plastic and couldn't be squeezed! Once you do get it to come out, the "brush" really just makes the stuff clump and glob up - it doesn't just brush on like you'd expect.<br /><br />Once you get the chemical out and use the system it works well, but I've lost so much of the chemical to bad packaging that now I need to order another set of vials to finish the treatment. It's not cheap, unfortunately, so I hope that they come up with a better packaging method for future purchasers so there isn't so much wasted whitening agent.
