I was very pleased with the results of this product. I noticed that my teeth were much more white after the 1st use!

My teeth were stain and I could not put on red strip for an year. I try other natural method and it did not work out for me... Eventually, I bought this and I definitely noticed after couple times. After 3 treatments I feel confident enough to put red lipstick and don't feel like my teeth is yellow !!!! I am happy with the result. ( I had a minor stain )

I ended up getting this kit as this was my first time using any sort of whitening solution in my life. I had my doubts but the reviews convinced me to give it a try. I've been using it for about five or six days now and I can't believe it actually works. My teeth are about three shades whiter than before. I do get a tiny bit of tooth sensitivity right after the treatment but that is usually only if I drink a cold drink. It typically goes away after an hour. It tastes what you'd expect it to taste like, peroxide. I have no damage to my teeth so far so I recommend it.
