Certainly by buying this item you can not expect to have the same precision as a drill column. However I find that there is still some play between the bars and the drill stand: drill ready to break down, there has between 1 and 2 mm of play, if one makes a hole 3 to 4 mm AC diameter is still a good standard. The suction function is convenient but plastic still blocks the view of the hole to be drilled.
The handle is not very convenient to assemble, disassemble and it should be if we want to put in the box. (The nut should be kept in place).
Before buying remember to check compatibility with the drill: the diameter should be 43 mm (some cheap drills have a diameter of 40 mm and thus unusable with). Sure does not work with most cordless drills (except a model of Metabo).
