First of all, this is a beautiful mouse. It's sleek and chic and fits perfectly with my gold HP Pavillion. It works great and it's not bulky feeling when touching it. It's nice and light. The only negative is it came with a dead battery, but a new battery was the simple solution. Overall I would definitely recommend this mouse.
I really love this mouse. It's slim and light weight, but feels good in your hand. Roller ball is of nice quality and the buttons have a nice tactile click. I was worried at first about the usb dongle but then discovered it's storage spot in the battery compartment. Speaking of, how cool is the magneticic battery compartment cover?! I love it. It fits in my slim laptop bag without protruding like a lump - excellent value for this little mouse
