The speed control is just "the finger". Otherwise, the machine is also not as fast as the one they need. For typical work we "hole in wood, Mark, hole in wall, bolt through." the machine is to act super, just because the wood, the stone drill and the bit holder can be used. Otherwise, it takes all of 5 Series to 10ner, sand-lime brick to concrete all not necessarily fast but stubbornly and without complaint.
Perfect is that the charging station can be visited without the battery needs of the machine. Only the selection at the drills is limited, but tolerable.
