Works great! I used it to take down a large waterfall fountain: cinder block wall with field stone face. Block had concrete and rebar in the holes. This tool handled it. In the U.S. it worked on a 120V -15 Amp circuit, no blown breakers, even with 50 ft exten. cord. I tried feeding it 220V power and while the extra power seemed nice, the timing of the strike/hit was not right so it was hard to get the tool to engage. And i burned up the tool in a couple hours. So do not try this! I bought a second one and had it n 2 days. Still going strong.
