Summary: I have contacted Gear Head for a RMA to replace this defective one. But will the replacement be any better?
Pros: Feels good in your hand. That's about it.
Cons: Very poor connection distance, it keeps freezing up from 10 feet away. The left button will stick making multiple mouse clicks or none at all. I had to replace it with a cheaper one from local big box store. The cheaper replacement one works flawlessly. So my recommendation is don't buy this mouse!
Summary: We tried everything and even called in a Geek but could not get this mouse to function at all. I'm returning it to our local store and will purchase a Logitech. I've had the Logitech for 2 years and haven't had one bit of trouble.
Summary: I'm still trying to figure out what the DPI button on top of the mouse does. Just as a rough test, it seems to toggle sensitivity or increase / decrease dots per inch between two settings. Some complaints were pointed to battery life.
Pros: - Decent weight - Super inexpensive - Mouse Wheel scrolls well (i.e. not fluid -- individual notches felt) - USB sensor deposits inside with the batteries - Tactile feel on buttons and side
Cons: - Battery cover a little annoying to get into - Batteries needed to be forced into their spot - "Gills" on the side of the mouse will probably collect hand oils and dust and be annoying to clean
Summary: I had this mouse for less than 6 months. It started getting sluggish so I replaced the batteries. After that, it wouldn't work at all no matter what I did. I even put the old batteries back in it and it still wouldn't work.
Cons: time to replace them about the time the batteries go dead
