Pros: Excellent! Works with computers, printers, etc other than what's listed.

Cons: None so far. it's a bit larger than you might expect, and requires use of the included AC adapter. Just account for another wall wart on your AC power strip. Understand that you'll need to plug this into your computer first, and set it up. From there on, it should work in another device. I've set up an older ethernet printer to do Wi-Fi, and also an older Mac.

Pros: Very small

Cons: This design is terrible - small, but the plastic separates from the metal very easily. HP awful - wouldn't replace it, since it still "works" but is physically broken.
