That part is really the last! Very cheap processed. In Endefekt which is nothing more than 2 cheap plastic trays with a not very long haltendem disposable substrate, which is not exactly cheap in replacement. The biggest hit was but when I unpacked the crap. The I quote: "patented splash guard" (nichst further than another platikteil which holds the pellets and for which ensures nothing splashes when ranstößt) was bent at me because during the transport the heavy granules weighed out. The "patent" was certainly not advertised on the material to when I just tried to push just broke it immediately. All in all a real scrap heap. The name is used again to customers as to lure me, who trust the quality assurance of such a company. They should rather stay with the glue. Who does not want to burn his money here should prefer no name refills for such pick "devices" and simply raised place in a bowl. Total cost not even one-fifth as the price of this product fraud.
