Cherry Passenger Black 3 Buttons 1 x Wheel 27MHz Wireless 1000 dpi Travel Mouse - OEM

Solid feel and responsive mouse, has the standard setup and the little power saver touch is definitely cool

Can feel a little large and on the heavy side at times, but you get used to it pretty quickly

Great feel, very solid, very smooth. Feels substantial in your hand. I have fairly large hands, and this thing fits my palm perfectly. The little door for storing the USB transmitter is a neat idea

Virtually none -- the aforementioned door for storing the USB transmitter could be more intuitive I suppose
