Since there was only one manufacturer of these Whitstrips many years in Germany, there was of course no great comparison. For some time, but these are no longer acquiring why an alternative was needed. Apart from the fact that these are even cheaper than the glare ..., these are my Meihnung effective after even. Firstly, they have a much better grip and can therefore also the 60 min. these must be taken to be kept without problems in the mouth. And secondly, the whitening can be seen as already described really well and very quickly. I drinke much tea, discolor in my teeth always something. These Strips 2 X per year, and the tea is no longer a problem.
