Review (4/5): Easy application
This product is currently on the trial period and so far I haven’t seen any improvement to my teeth after 2 weeks. I’m hoping it will help my teeth become whiter. The good side about the product is the neat packaging and how easy, simple, and practical way to use it. With a thin layer of the gel, brush it on the teeth, the taste is somewhat tolerable, then let it dry for 30 seconds and no more rinsing.
