Property me the kit purchased at a multi-hammer and tried all the parts on my walls at the weekend. The chisel work great! For slots you do not necessarily have the gouge, the chisel works just as well, but when he is at it, you nutz him halt. The drills have a few holes nor its pointed tip, but eggs without end. If you want to have really precise dimensionally accurate holes, should rather acquire drills of other quality manufacturers. For my application (electrical installation), it was enough this time.
Price / performance so well. Quality okay. Suitcases practically.
