Review (5/5): RESULTS VISIBLE AFTER FIRST COUPLE OF USES!
I was able to notice a difference after just a couple of uses! I continued to apply the gel to my teeth for 2 and a half weeks (and I suggest doing so for best results). Another great perk of this specific product is how easy it was to use. Many other teeth whitening products that I saw on Amazon were complicated, or simply ineffective according to the reviews. But this one goes above and beyond, and you can very easily notice your teeth get whiter over time. There were also no sensitivity issues whatsoever (although it might depend person to person). Overall, I would say that this is the best tooth whitening product you can find on Amazon, and the affordable price, quick shipping, and trustworthy seller will definitely make you happy (and your smile brighter :D )
