A little too impressive, tool, when it is discovered. But in the operating empty, quickly understand how it works. A tip: be aware clamp them to do the work.
Otherwise, the crimping tool crimps well because she greenhouse good 2 metal thicknesses before punching them and that is awfully when mounting a partition with metal rails.
Well as practical: when one punched metal and then change your mind, you can remove the crimp with a screwdriver (as when removing a clamp by lifting one side closed)
