Easy recognition on Windows 8.1 and 7. Design out of standard mice. Requires an integrated blue-tooth to PC or Laptop Dongle or already acquired. Shipped from Holland by mail, routing still took more than 15 days. The packaging was a little light, it came a bit squashed but the product was intact. You can set the resolution of the mouse, but there is no knowing at what level it operates. The instructions are only in English on a single sheet of small size, provide a magnifying glass .... No batteries included, it's petty to me anyway ...
