I was very surprised how messed up Bosch was. And not green, but blue, which, as stated, is designed for professionals. Barrel broke after a month of work. Replacement for my money. Then the start button fell apart. Likewise. It burned out after 3 months. The electric motor is covered. Repair repaired and sold out of sight for half price. For the rest, I bought a similar one from another brand, but, as practice has shown, it is much more reliable.
