Had regard to the reports of the partly somewhat spongy keys are no objections, because I'm playing the piano rather fine motor tasks on the go with your hands. But just the three side thumb buttons are marked mimosas and you click at the slightest touch AB. The thumb is indispensable but if you want to grab or hold something, and the mouse will be out. But this is the only really relevant and criticism. The design and workmanship is exemplary, even the cable has a textile sheath. Stable as it is, because it is already a couple of times slipped off the table and popped onto the dance floor when I caught myself again in exemplary long USB cable. The pulsing, glowing light effects between the scales are really an eye. The software to configure or driver you have to download from the website and could have been a little better documented. Meanwhile, I look at the mouse as a collector part. I'm glad to have the mouse, and that is what matters really only at.
