Customer Reviews of Image Wireless Finger HandHeld USB Trackball Mouse with Laser Pointer - Wireless - Black - USB 2.0 - 800 dpi - Scroll Wheel - Symmetrical
A small receiving device plugs into a usb port on your pc so this operates wirelessly and, so far, after the initial charge I haven't had to recharge the mouse after 10 days of use. I would recommend this to anyone who is looking for an alternative to using their touchpad or wants to give a presentation from their laptop/netbook and walk around.
This mouse works great, but haven't figured out about lazer pointer.
Great Idea but too glitchy4/28/2012
I bought this mouse because most times I don't have space for a mouse and when I seen this I thought well now I don't need space as its handheld. It works pretty well, I rated the performace a 3 because the moving ball has a delay in it most times where I'm moving it but the mouse on screen isn't moving. If I shake it in my hand then the mouse on screen starts to move fine again but I believe there is some software issue as it happens every 3 mins.
