I use this mouse for my laptop now since about a month. I have taken time out of the package, have opened the original packaging and have the mouse simply connected to the laptop. There is no additional installation of any software necessary - it's all automatic and it works only once! Furthermore, the small receiver is very useful, because the does not break off. You can put it even in the laptop bag or leave Bagpacks tuned ... The range now I have not been so precisely tested, but I kan report that I've never had problems that the mouse was out of the reach or that the subsoil was weird and thus the mouse had misfire. They even work on my bed sheet (stinknormal white with absolutely no pattern) properly !!!
I am really very happy with the product and would also recommend to everyone, he is still looking for a good portable laptop mouse! For the price simply unbeatable !!!
