The Thermaltake Level 10 M mouse is the second collaboration between BMW Designworks USA and Thermaltake, and it's a conversation starter, if anything. Call it streamlined: the body is made of aluminum, but its sparse innards are exposed revealing quite a bit of empty space. It's surprisingly light, and fit snugly in our palm. We couldn't actually strap the mouse to a PC and give a few games a go, but our limited hands-on time didn't disappoint. A honeycomb pattern on below the left button serves as ventilation, improving airflow and (ideally) keeping your palm dry. The mouse is height adjustable by way of a socket set into the spine, and the palmrest can be tilted to either side by five degrees, increasing your chances of getting a decent grip.
