How can I describe it, delivery time only one star. the extra packets in the roads hardly worth. The quality of the brushes yes ... one I placed but with real pressure now I'm curious whether the again goes off when it is worn. The bristles are soft and rather see already when unpacking from as needed, not to be compared with the originals. The originals are of high quality much better, but as cost yes 5 piece already 13 - and 20 10, -. The Puztergebnis is good after 1 week use. The brush can go well again, I've just tried. In my message after about 40 days delivery time then came within a little over a week at the new delivery. There was an apology from the company. With the quality because we'll see how that develops in the coming months, of course, price unbeatable but then how many of the workers actually earned? Today on 22/11/2014 I can now draw a conclusion. It's not clear, I pay rather more for brushing as for a dental prosthesis. The difference between the originals and the cheap is like night and day. The fit of the cheap toothbrushes is simply not given. A brush head has a bit scared to spend so much energy to put on (the handpiece cost you even a lot). The originals brushes sit right the first time and one can at the color gradation of blue bristles see when a change has to take place. For approve the bristles are already broken without there is a change in color. For me clearly - I will not buy cheap - quality mies - Quantity super. One could compare it to a company builds 10000 submarines only 10 of which come after the first dive back - the others are missing. Do not buy.
