Excellent dock mouse
I've been using it for 3 years now, it's really very ergonomic, light, no latency problems, the Razer software is well done and my charge is really good.
Nothing to complain about in terms of the mouse, the buttons or anything else, but the dock, on the other hand, unless you clean the pins on the dock and the mouse with alcohol quite regularly, I just charge it with wires most of the time.
