It arrived, I opened it, I tried it, if it works, I didn't like its performance... and then I left it on the bench, simply plugged in. At some point later in the day, there was a bang and smoke came out of the tool. I sent it for replacement, now I'm waiting for it to be approved for replacement. As for its performance, it has nothing to do with any well-known brands... I didn't use it for cutting or grinding, I didn't even have the chance, I just plugged it in to see if it turns on. It might have been a coincidence, I will come back with an update...
