Summary: I purchased this to replace a 3000 series mouse that was old... it worked better in my opinion, this mouse does not have the distance the 3000 had, if I go to far away from my laptop with it it will start to flash and you have to disconnect and reconnect the usb stick.
Pros: Very nice mouse! Works on almost any surface and remains accurate and smooth. The fact that it doesn't have too many extra buttons I think is a plus for a portable mouse. The dongle secures well and is convenient to carry. Good battery life.
Cons: The scroll wheel used to be smooth but after about a year started to be harder to scroll at one spot. Had another mouse like that and the right button was a little hard to press.
Summary: All mice labeled 'wireless laptop laser mouse' should be bluetooth enabled. I didn't buy it from newegg because I needed it right away. If I had, I would have got the one I wanted, and it would have been bluetooth. So not buying from newegg cost me.
Pros: Small, light, precise, easy to shlepp around. Doesn't feel awkward or complicated. Connects without drama.
Cons: Ejects battery when getting receiver from base. Poor design in where battery goes. Feels light like child's toy. Magnifier button is handy, but it's right where the 'back' button should so you hit it be, so you hit it when you shouldn't.
