I bought it in January (2017) and use it every day. The battery lasted over six months; which is almost right for me. I have also used the Logitech, Dell and MS brands in the past and this one is comparable to them. However, I agree with other reviewers that this is a little underpowered. For a physical comparison (before purchasing), please check the size of the Logitech M317 Wireless Mouse. Walk to the closest target to see how it "fits" in the palm of your hand to be sure. In any case, the size is perfect for me as my laptop sits on top of a TV cart and that's where I mostly do my "work". So if you're a workstation fanatic with limited space, I wholeheartedly recommend getting one.
