Good Bluetooth mouse. Easy to setup with single AA battery. If you have a number of Bluetooth devices, you should switch off the mouse when not in use or the battery will run down quickly.
When the HP240 Mouse is connected with my HP computer, everything seems to work fine. But the problem is connectivity. When I start my computer. the mouse never connects immediately even though bluetooth settings seem to be set up correctly. It may take more than a half hour for the computer to connect to the mouse. My only recourse is to never turn off the computer or mouse, just close the computer screen. That way when I open the computer screen, the bluetooth mouse is still connected. This is a really frustrating way to operate and I am not happy about this.
