At Bosch, I found it. Moreover, this gun is small and handy and easy to use. Even a child can handle it, and thanks to the small nozzle and the much smaller "ammunition" simply succeed even finer work. The charging within 20 seconds is completed and you can start.
We have worked a lot with it since the purchase and are thrilled.
Too bad that the battery is not replaceable, but this would be of interest only to the defect. Otherwise, I am happy with the battery life and short charging time.
