I knew perfectly well what I was taking and why, the shortcomings did not bother me much, they did not interfere with my tasks, and the task was mainly to assemble and disassemble computer system units, including plastic cases of monoblocks, servers, server racks and similar computer kitchen . Occasionally tighten self-tapping screws, nuts and drill small holes in plaster, wood and steel up to 2mm. The tool copes with these tasks perfectly well, thanks to a well-functioning gain control, it combines for me the needs of an electric screwdriver and a screwdriver itself and a small drill. If you are a system administrator or an anika, take it boldly, it is definitely worth your money.
