Disgusting. The tool was lying for a month, but they could not repair it. They only fed on promises. I took it to another service (I do not write that they would not consider it advertising or the machinations of competitors), and everything was done in a couple of days. The director (he is also a repairman) could not even determine the cause of the malfunction. I strongly advise against it!
The man with the nickname Alexander Karpovich, who put 5 stars higher, is the director himself.
I gave the Watt WWS-1100 grinder for repair, it started buzzing, it was already scary... We changed bearings, brushes, grease and it worked like new) We did it quickly, I just had time to go and drink coffee.
