Query: Be aware of battery issues

I've never written a review here at Amazon, but I felt compelled to let other potential buyers know what they *might* experience if they buy this mouse.Before buying, please be aware of the (reasonably common) issues with the built-in rechargeable batteries in this mouse. Go to the Logitech forums (forums dot logitech dot com) and read what issues people have been having with the batteries (inability to recharge, frequent loss of mouse precision due to battery issues, etc).Don't get me wrong: this is a lovely mouse, truly well designed and a joy to use when it's working. Unfortunately, there's an apparent flaw in the battery charging system that makes some mice unusable.Until Logitech either issues a recall or openly admits that there's a quality control issue with the MX Revolution, I'd suggest anyone seriously reconsider purchasing this mouse.
