Summary: Nicely packed. The photo of it as small as in the palm is a little too small from reality. the buttons are sleek, good click response, good scroll response. Invisible optical laser that works perfectly well. Extremely happy with how it fits under my palm. Recommended. UPDATE after 2 days of usage: The battery died. After just 2 days of use? The packaging says 12 months. Other reviews says a year+ easy. this is ridiculous.
Summary: This really is a small mouse; my hands are not huge but it's smaller than my palm so is taking some getting used to (I used a Genius traveller mouse for many years, which is not much bigger than this one, with no problems). I've also had to adjust the mouse settings (Sony Vaio laptop running Win 8) as at first I was getting a lot of spurious cursor movement and things were being selected at random.
