Query: I do not recomend this mouse

When my screen saver comes on I have to hit the very small connect button on the receiver and on the bottom of the mouse, or the mouse does not work. It is very small and not ergonomic. You have to be within 2 1/2 feet of the receiver in order for it to work.On the upside, when it does work, it is perfect.
