I have this angle for a few days in use (unfortunately got him at the hardware store bought expensive than it is offered here on Amazon ... well ... your own fault!) And can not quite understand the bad reviews zt. In detail: the device is through the mount in 3 different positions super soft grip in the hand (the one with the built-in control keys for the disc, I find a great idea, so you have the key to change the disc always there). The cable can be wound up by the handle and are secured to a clip. I have so few Baustahlmatten decomposed or tailored (AQ-60 mats) and a lot of scrap processed for Altstoffsammelzentrum, this task has made the Einhell device super. I can about the longevity unfortunately not comment, but it seems to me the device is not as if it would be limp in the near future. The on-off switch is the only criticism I can understand (a bit "fiddly" on and off), the other can (the "Blue" and "Green") better. But otherwise my buy recommendation and for the hobby.
