This is another mouse I bought recently. Excellent workmanship went into it. It's made by Logitech. The model is the "VX Nano." I bought it off of ebay for about 60% of what it was selling for at normal internet retailers, and half of what it was selling for at my local office depot.

It is a laser mouse, and as such, it will track well on any surface that isn't reflective or clear.

As you see, it has a little wireless receiver, and the range is excellent. I could easily use it from the next room fifteen or twenty feet away, if I wanted to, and I have done so, on occasion.

It has a nice suave little compartment on the bottom for both the batteries, and to store the receiver when not in use.

It takes two AAA batteries. I don't know the full extent of the battery life, but I haven't had to replace them in the month since I got the mouse. So, it appears that the battery life is excellent.

If you are using this mouse with a microsoft windows operating system, there are many ways you can reprogram the buttons to do specific things for specific programs. With the left and right mouse buttons, you can only swap them, you cannot reprogram them or turn them off. And unfortunately, you cannot assign a combination of mousebutton plus keyboard action to any of the buttons. I had hoped that with this mouse I could pan and zoom all from the mouse on my 3d modeling program. No such luck.

You see there are two extra buttons way up front on the left, these are really accessible only with the fingertip, not with the thumbs as is the case with other multi-button mice. There are two extra actions you can get by tilting the mousewheel left and right. If you press the scrollwheel you change the action of the wheel from indexed to free-spinning. The middle mouse button, as you see, is right there behind the mousewheel.

The free-spinning effect on the mousewheel feels really nice under your finger, and it's efficient for spinning up to the top or the bottom of the page quickly. However, most programs out there expect the wheel to be indexed, and so they'll scroll windows in a clicky fashion, even though you'd think the motion ought to be smooth. Also, the free-spinning wheel means that if the mousewheel is moved a little accidentally, unexpected things can happen on your screen. On the other hand, the indexed mode of the mousewheel works just fine, but feels rather sloppy under your finger. There's a texture to the vibration when it moves that feels as if the mechanism wasn't machined properly inside.

The mouse is about equivalent in size to the typical ball mouse seven or eight years ago. It doesn't feel small to me, but it will certainly feel small to many people who are used to using newer bulky mice. It weighs 3½ ounces with the batteries.

Sadly, this mouse is way too heavy and large to be comfortable for my hand. I started feeling the wrist strain within half an hour of use.
