Pros: Very simple and to-the-point user interface. 'On/Off' & 'Temp'.

Cons: Fan noise. On the plus side, it reminds me the unit is on.

Pros: Price, size, appearance

Cons: Too many dropped/spurious characters. With Win 7 Notepad, it took me a half dozen attempts to close the app after a typing test. I was using the menu bar. I kept getting hits on Save as... and Print... etc.

Overall Review: This item is a *lot* smaller than I was expecting. Rereading the description does give the dimensions though. Does not seem to work via the USB cable. Wireless is required. I'll keep it because it's kinda cool and with more use, I might be able to make it work better.

Pros: It just works. I have no idea how many of these I've purchased. I support multiple machines and all are equipped with the Trackman. I lend them to friends and never get them back.

Cons: None

Overall Review: Don't eat salted peanuts in the shell while using this mouse. The dust soon makes it very difficult to roll the ball. Five seconds with a tissue and you're good to go though. Can't speak for other mice.

Pros: I used two of these devices in a RAID 1 configuration. No problems at all.

Cons: None

Pros: Built a new machine for my wife and purchased this as part of materials. She likes it a lot.

Cons: None

Pros: VMware ESXi 5.5 U1 acknowledges and uses this NIC without any problems.

Cons: None.
