Purchased from Revain Certified. The mouse came in a plain box, which is not a problem for us. Includes USB extension cable, mouse, receiver, battery and documentation. The right mouse button did not work properly. Almost no pressure was required to activate. I couldn't even surf the web without pressing the right mouse button. Also, the mouse's crevices were filled with dirt/dust, which was quite annoying. The Revain return process was relatively easy. It was only โฌ5 cheaper than new. Itโฆ
