The blade is stable and does what it should. Only that is used or change the diameter at the Isio a question of patience ... so just click out / click purely ... is not. Since Bosch should rectify again ... because if I had known how hakelig the knife Swap is, I would not have bought the device. What good is the best (and sometimes expensive) and most reliable device or quality accessories when changing the accessory becomes an adventure.
PS: still have a similar device from Bleck & Decker where there are no more spare batteries unfortunately after 15 years. since the change of knives click works out / click in.
