How well does Rembrandt 2 Hour whitening kit work?

Can you use 2 hour teeth whitening strips over a period of a few days instead of all in the 2 hours?

• is the effect the same? The Rembrandt 2 hour whitening kit has four 20-minute sessions and it is supposed to be done continuously for two hours, with short breaks in between each session. Insteads of doing it all in the two hours, can I spread it out, use one a day? Maybe two a day? I'm just afraid it will be too harmful on my teath, that much bleaching in that much time. But I still want it to work, so can I spread out the sessions 1 per day and still have the desired whiteness, or does it have to be done all at once to really work? and does anyone know if this harmful to your teeth? I trust this brand, I mean there toothpaste is a woping almost $7 but I use it and it does work. And it claims its enamal safe and all but doesn't everything?

• Answer:

  When I tried the teeth whitening strips, I personally only saw a small difference. Maybe it was because I didn't always remember to use them. But either way something that's a lot more effective for me was Idol White. I liked it because I took it with me and it was more convenient and effective than the trays and strips.
