My impressions so far have been purely positive, I immediately hung up the chandelier, and tested the perforator on the little things at home there. I am new to repair, but I wanted to buy a model with a margin of safety and reliability, the choice fell on this model. I still have to do repairs in the new apartment, I think everything will be ok, it feels comfortable in the hand, the assembly is of high quality, inspires confidence. The case is ok, but putting the cable in there is a little troublesome. The functionality is also pleasing, you can use it as a drill, or just gouge the wall. I am very satisfied with the purchase)
