I do it often, but here I must sometimes submit a criticism. Note: the device was not ordered from Amazon, but bought in the Metro, is the measurement depends in no way against Amazon, but only serves to elucidate putative prospective. Shortly after the warranty (as heck be otherwise) gave it during operation of smoke and after a few seconds the mill stood still. After disassembling the unit revealed that the G-fuse (4A / 250V) was blown. To get off at all the driver board had expanded and after that the fuse be unsoldered. It is probably not believe that such a part is ever repaired. Quite apart from this, one comes without a Secure Torx screwdriver not unscrewed the bottom cover. After replacing the fuse began - albeit stuttering - the engine again, but the brush sprayed on the commutator as sparklers for Christmas high season; Immediately he ran under smoke hot again. Fazit1: Scrap! The engine is of billigster construction and - how shall he be any different - manufactures in China. For the high prices you can rightly expect more! For handling, I can only agree with the negative attitude reviewers. A 100% cleaning was not feasible - the supposed self-cleaning does not really sufficient. Furthermore, I had to grab my wife when Wegschrauben the essay from time to time under the arms. Fazit2: A little electronic gadgets makes no valuable machine! You deliver us from Chinakram! Zero points = one star, because it's not done differently. Nevertheless, Happy Easter!
