I have the whiting kit and so far so good. I drink tons of coffee so I anticipate a slower progress rate. I do wish this kit came with a chart so you can see where you are at and where you should be. Overall I had zero sensitivity and my teeth are usually super sensitive! Left in the whitening gel for almost 2 hours with no issue!
