Logitech G604 Lightspeed Wireless Gaming Mouse, Black

I have bought two of these mice for different work stations. The multiple buttons on them are easy to program with the software and the battery life is better than the old Logitech g602 I had. I get a few months on one AA battery. For the features it has, it's a good value at it's price point. The biggest con is it won't work with the Logitech unifying receivers as it has its own USB receiver but it's not really a problem unless you are low on usb ports or move the mouse between PCs frequently. Bluetooth helps to negate this issue and the Bluetooth functionality is good

Outstanding mouse! The 6 customizable buttons were a surprise and they are super powerful if you know how to use them. I programed them to snap my windows between left, right, or full screen. I also programed buttons for back, forwards, undo, and zoom in/out. You can also make profiles, so you can have a web browsing profile, profile for gaming, or one specific to an app. It's marketed as a gamer mouse but it's really a secret weapon for productivity. I'm going to see if I can shortcut common Excel functions next. Only downside is that I can't figure out how to have two Bluetooth connected devices. One computer has to have the dongle, and one has to be connected via bluetooth. Wish the device could switch between two bluetooth connections
