Review (4/5): Worked Alright
I've never whitened my teeth before, but I'm generally happy with this product. It noticeably whitened my teeth, though not extremely. I have a bonded tooth and the whitening looks fine on it, it doesn't stand out to my eye compared to my natural teeth.
I followed the directions and applied 4 applications of gel/light every day for 5 days. Each tube/container of gel lasted 2.5 days of use, meaning ~10 applications. That was even with using a lot of gel each time and not squeezing out every last drop.
The taste is like weird mint toothpaste, it didn't bother me at all. Actually the lip balm tasted worse, but I do recommend using it each application, it helps. I have sensitive teeth, but didn't experience any sensitivity or irritation.
I did get the gel in my eye once, I was pointing it at my face to see if I had squeezed enough gel out and an air bubble popped. It stung, but I rinsed with water for about 10min and it was fine.
