Review (5/5): Love it! Never using whitening strips again.
Love this! Just bought it a little over a week ago and have been using 4x per day. I’ve been using whitening strips from home for close to 8 years now, even the high end Crest strips and this beats out everything I’ve used before by a long shot! Not only did better whitening strips cause extreme tooth sensitivity, they never whitened like this does. This will burn slightly if you get the gel on your gums, but it’s minor and easy to wipe off should you get it on your gums. It’s a pricey item but it’s completely worth it! Especially since refill vials, I think for like the 10 pack, are like $45 bucks, cheaper than a normal whitening strip pack.
