Query: Great notebook mouse

This is a great notebook mouse. Battery life is great. it's small, but form factor is great. very responsive, best notebook mouse i've used.Now, the reason I gave it 4 stars. Mainly because I believe this is a design flaw. The receiver snaps into the bottom of the mouse, shutting the mouse off and making it easy for travel. That's terrific. However, there's no other way to turn this mouse off. Not an issue if you're only using it to travel, however If you sit down for hours at a time, this may not be the mouse for you. There are times where I leave where I'm sitting, and want to turn the mouse off. The old logitech notebook mice had a switch on the bottom of the mouse to turn it off. So if you left where you were sitting, you could conserve battery life rather easily. There's no such feature on this, and removing the receiver from your USB is a less than optimal solution.Other than that, great mouse.
