Negative Positive
Title: Pretty disappointing
Review: I'm not very happy with this mouse.- Very, very laggy. Presumably to improve battery life, it goes to sleep constantly. You're always having to wiggle to wake it up, even after just a few seconds' typing.- Charges batteries slowly, and does not work at all when batteries are dead, even with USB cable plugged in. So you'll leave it on the shelf for a while to find the batteries are dead, then need to plug it in for a long time to get even the minimal charge needed to use it.The one pro is that it's quite precise, and has a precision-enhancement mode with even higher DPI, but that's all for nought since you're having to fight its narcolepsy all the time.Size is just big enough not to fit easily in a tiny part of a bag, but still small enough to be non-ergonomic. The worst of all worlds.
Is the review positive or negative?
