totally superfluous, if not counterproductive

I can agree with criticisms only two: the absolute dreck! just a cordless screwdriver with plastic / wood borers and vlt a small wrench, so that it is much easier when you reindrehen.
drill did it with me a 5mm (less here not better, if you think that - that's loch else like the original too small, pressing plastic inwards and so is he leaking). wrench (the opposite of hex) I think make würd's an 8-(I have not used, after seeing the "great" tool - with the appropriate dimension - already possess)

Update: better stick with a nail or the like a small hole and then take a steel drill. clean cuts and wood / plastic pricking easily a hole on the other side.
