I really like it as it allows to rotate batteries from all bikes with single charger, has easy indication of what batteries are ready to ride and seem to be slightly better made than 1-bat chargers.
This is what should have been the AXS battery charger from the start. The single unit is fine for travel and when time is not an issue but this one with the speed of USB-C and multi ports the job gets done way way quicker and you are riding sooner. Kinda expensive but you would only be buying once, so for me worth it.
