Title: Great Mouse but very poor battery life
Review: I agree with positive reviewers concerning the excellent precision and smooth performance of the G7, but if you spend a decent amount of time on the computer daily you will hate this mouse and Logitech. What will happen is that you will quickly tire of having to swap to the spare battery every day or every other day. What's worse is that you will soon realize that the G7's batteries are propriety and there's nothing you can do about it (i.e. buying more powerful batteries) short of returning the mouse. How Logitech can sell a premium mouse with no battery life is beyond me. I guess that's why they give you the spare battery that is always charged. That, however, is just a band aid covering a power hungry design that is a great annoyance.
