The ergonomic mouse I talked about earlier was an almost instant relief on my lower arm muscles. Therefor I would like to have something like that after having to send back the previous ergonomic mouse.
This resulted in me searching for alternatives and ultimately ordering the Logitech MX Vertical mouse. It arrived today and it instantly worked. Although this mouse also works via Bluetooth, it did not stutter so far. It works through the Logitech Unifying dongle.
Some pretty pictures:
