The mouse looks great and is a good weight with built in batteries. The mouse is a bit small for me and I have a pretty average hand size for a man. It has a glossy finish that is easy to keep clean. The pads on the bottom are smooth and sleek. The buttons are responsive and comfortable. Now for the bad. The mouse was DOA. Tried the batteries that came with it, nothing. They tried the batteries I had on hand and again nothing. I am trying to connect via Bluetooth and button presses as mentioned in the manual are not responding. I saw other reviews about downgrading Razer products. I thought it was just an exaggeration but now I'm inclined to believe they are correct. I would probably look elsewhere for a bluetooth mouse.
