Pros: Dancing colored LED lights.

Cons: Doesn't work.

Overall Review: I bought two of these on newegg. After you connect it to a Windows 7 or Windows 8 PC, it will work for a few minutes and then suddenly the left-click will just get stuck. It's defective manufacturing since both mice had the same problem. It will cost you more to RMA the mouse back so just don't buy it.

Pros: First, you''ll need to download the latest driver. Tested this adapter on my latest Windows 8 gig and an older Windows 7 build. It consistently drops both the 2.4 Ghz and 5 Ghz ever few seconds. A 5-second 'Selective Suspend' property was enabled for some reason by the installer and I disabled it but somehow this one is just not a stable enough of an adapter to catch any of my various 2.4 Ghz or 5 Ghz signals with a reasonably linear inssider time graph. And that's with two antennas only 15 feet away and within line of sight pointed towards a Cisco router. Interestingly, a cheap dual-band USB wifi adapter doesn't drop signals but this one does.

Cons: Can't be put to any practical use unless constantly rebooting Windows PCs is a passion of life.

Overall Review: Manufacturer ought to thoroughly test adapters for dropped signals before putting stuff like this on sale through Newegg.com.
