I am very pleased with the set, there is nothing superfluous, everything you need is at hand. I advise you to buy a kit for a new or old screwdriver. Its pros: Convenient set of class "Everything you need at your fingertips" Cons below: The remote bit holder is a bit crooked, it does not particularly affect screwing in, there is not enough concrete drill for 10, and just the smallest one is not useful.
