Input: I obviously don't know about battery life as I just opened this. So far not very impressed. It's okay ...BUT, not very responsive on the the double-clicking. I have to focus and make sure I do it as fast as I can....and I have to keep clicking repeatedly to make it work. That alone will bug the heck outta me, but I can adjust I suppose for the price.<br />I'm just concerned about the battery.<br />$8.00 isn't a deal if it eats batteries.<br /><br />Update 2-6-2014 (3 days later)<br />I was generous giving it two stars when I first reviewed. It now is down to one star as it will work only as an emergency mouse if all else failed....but only that.<br />Scroll wheel rarely works. I have to grab the scroll bar on the side of page or wherever I'm at to move the page.<br />Also, it was good at first, but it already doesn't track well on a mouse pad....on a flat desk is okay but I can't stand the feel of that and it's an antique oak desk.<br />Not going to ruin the finish for a cheap mouse.<br /><br />I could have tolerated the crappy clicking .. the wheel issue and tracking are definite deal breakers....purchased two...they are going back.
