Bosch, wow. Who is the set for, a schoolchild, for training, or on a shelf for beauty! ? Several drills from the set are frankly curved in an arc, for wood in particular, and one feather drill, soldered drills for concrete - they DO NOT DRILL a normal wall! Frank trash - even for homework, not to mention the masters-pros!
To complement my words, I've added some photos that capture the essence of my experience.
