Delivery time 5 weeks but finally I got it in two weeks (product from China) .L'emballage is a little summary. I bought it for my area and it works perfectly on Windows 8. The connection is super complicated for me because the manual is in English and not very explicit. Fortunately there were comments to help me connect :) For those who are in the same situation as me, you have to press the right click, left and roulette at the same time when the mouse is "light on ". Otherwise for now, it works well and I would recommend this mouse as it also has a normal size and not too small.
