Battery Life on Logitech MX Duo

[Grizybaer]

I have the old logitech cordless desktop pro. The battery life for my KB / mouse is about 3 months / 1 month respectively. I noticed that the new Cordless MX requires 4 AA as opposed to my 2AA. How is battery life / range, or if there are any other noteable differences, please post~!

Thanks

The keyboard goes a long time (at least 3 months).... Mouse doesnt matter because its rechargable and every night i put it back on its base.
