The entire set is well designed and very extensive. However, the wrench due to the incorrectly positioned switch is cumbersome (you press it with your thumb from the top). Bits and nuts are plentiful and will definitely last longer than the screwdriver because the battery is scrap. My screwdriver has just survived the guarantee, then it was over. I'm going to invest in a new battery, because the set is really too good for the bin. By the way, there was the same Schrauberset at the hardware store, completely in yellow from another provider. So quality of Makita ???
