Cheap and slow working
I tried this product for a week, for 20 minutes a day. My teeth got slightly whiter, but I had to stop using the product, since my gums got really sore. The whitening effect is really weak so it would require many treatments to make a big difference. The mouth guard is so badly formed that it was impossible to not get it on the gums. It didn't fit snugly to the front teeth, so the product came off quickly. I might try it again with a custom shaped mouth guard.
