Summary: Upon initial setup of the mouse, I had to work out some kinks, but if you have the right computer I think this mouse works perfect. I see lots of people complaining that this mouse doesn't work the way it's suppose to. However for me it works as expected and I don't even use the mouse on a daily basis. The only complaint I would have is that the extra buttons don't really do much unless you have an HP laptop or something perhaps?
Summary: After installing the DVD included software, turning on, and pressing the connect button this mouse was able to connect to both my laptop and desktop computers. No USB receiver is required. Computers must have built-in WiFi.
Summary: The design of this unit is excellent, but there are no drivers available that will permit it to work with Windows Operating Systems except Windows 7 and Windows 8. It is not compatible with Windows XP.
Summary: I downloaded the newest driver and the firmware update from HP. No problems with installation or firmware update. I would recommend not using the cd driver that comes with the mouse but go to HP to get the latest software. I am using a Samsung laptop 2013 recent model and Windows 8. The mouse performs very well and fast response. I can use both the mouse and the mouse pad on the computer at the same time - this is a great feature.
