It is almost impossible to get a bit / drill out of the mold, you need to cling to the edge and swing it. Due to the resulting tension, the finger may come off and a drill is already sticking out in your palm, which is located next door or opposite. The rubber-plastic molds themselves are also very difficult to remove from the set. Either sit and bore / cut to size absolutely all the shapes and clamps, or have two pairs of pliers - hold the shape with one, take out the right bit with the second. And with your foot you press the whole suitcase to the floor so that it does not fly away. The bits are good, but the convenience of typing and the possibility of getting hurt will spoil all the pluses in general.
