HIGHLY RECOMMEND. I honestly was skeptical when buying this because white strips didn't really work for me and they hurt my mouth a lot. After the first 10 minutes, I was shocked I wasn't in any pain, and when I took the mouthpiece out of my mouth I even noticed a little difference (which I wasn't expecting right away). I stuck to it and 3 weeks later I honestly found myself smiling and laughing while showing my teeth, it had been years since I did that (I alway hid my smile). Wow. I owe Snow Teeth Whitening not just for giving me whiter teeth but for giving me confidence in myself again to show my teeth when I smile.
Bottom Line: Yes, I would recommend this to a friend
