I've been using the gel product for over a year and I get fine results. I use it as instructed and have no issues and see results. Not sure why other reviewers don't see improved whitening...perhaps not using consistently or according to instructions. I plan to continue using the gel. I purchase one at a time and don't do a subscription.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
