I was a little skeptical of buying a teeth whitening product like this, but after reading the reviews, watching YouTube, and the quick tutorial for the Purean Teeth Whitening Kit, I'm glad I made the purchase. After using it every morning, for the last 4 days, for about 22 min, my teeth seem to be at least 2 or 3 shades whiter.I couldn't use the product for the full 30 min, because my bottom teeth felt a little sensitive after the first 30 min use (possibly because I need to see a dentist). I still floss, because I don't want the whitener to whiten the plaque on my teeth, although I think it's doing that anyway.Because of Purean's effectiveness to whiten teeth, especially after brushing, I recommend this product. I definitely like having a whiter and brighter smile! I would also encourage people to purchase/use immediately after getting teeth cleaned by a dentist to keep teeth white and to prevent the product from whitening plaque areas. Lastly, I think the price is good too, especially given that all of the expensive whitening tooth pastes, including charcoal tooth pastes, and whitening listerines never got my teeth this white; Purean-2-3 shades in just 4 days!!
