This isn’t my favorite method to whiten teeth. It can be very messy and I feel like it doesn’t whiten as much as I’d expect it to. When I use it, I drool like crazy. I think there are better whitening products out there worth trying.

This works well and it’s super easy to use so that makes it 5 stars from me! I’ve used other whiteners that have burnt my mouth before but this is gentle and still works well.
