I agreed to take it for 5,400 dollars and eventually made a refund, the money was returned in full, despite the fact that it took a long time and was not convenient, including mail forwarding, waiting for a decision, etc. In a nutshell, who writes that this is a legendary grinder? It must be mammoths or makita drochers who are used to the old cumbersome equipment, à la Sov Soyuz. Some pros: Because the wire is not only gentle but also sufficiently long, there is no vibration, and it does not impact. Cons: It is cumbersome, there is no soft start, the housing is antiquated, and most significantly, the power button is difficult to press, and it turns on after the fifth attempt. The cost is excessively exorbitant.
