Who at that price a 41-piece High-Set expected is your own fault if he is disappointed ... Bosch "green" is very good for "Hobby-yourselfer" who the things 2-3 times a month in light use. Who does what only 1-2 times a year can buy the same Einhell ... For people who want to do more challenging work, I recommend Bosch Robust Line as an option and, where appropriate, for the ambitious handyman the Professional Series Bosch (ie the blue devices).
