I was really surprised at the fast delivery and was surprised to have to build the package himself still together. It was a guide and a tooth color template here. In addition, the 28 Whitestrips. I was really excited about the application, because I had read divided opinions about the product. But I went with an open mind attitude to the test, and was initially very confident. The application of the individual strips was really simple and very well kept! The taste, which develops in the wait was not too bad and unbearable. However, there was a bit sticky, so my lips are often stuck together. In addition, it grabbed my mouth slightly, but this should not be a negative side to the product. After the required contact time I removed the product and was pleasantly surprised! My teeth were really white and felt very good. However, my canines were only half know, because only where the strip really budge, he dyed. Unfortunately, they do not stay the whole day through white, but the effect disappears after a few hours. So for example, super parties or interviews. That's why, unfortunately, only 3 stars.
