I wanted to buy a product that I can use only for private use, since I as a med. Podiatrist not want to build my every professional device. Of course, I realized that I can not compare my professional case the small device, but even if a device is only intended for domestic use, the function should be still guaranteed. The router to wobble in the Halterrung and thus it is impossible to work with. In addition, the milling of very poor quality, so that you neither a filing effect has yet something happens except the noise of the engine. I have returned the device and me again stepped up a professional unit in a smaller version.
