Pros:maybe just a bit faster....if ur in line of sight.
Cons:must be line of sight, no reach, wasted my money
claims to be a bit faster (mbs) then my dell installed wireless device, if it is it's not much. have to be close to router...dell's device i can sit on other side of house. am using the correct "n" router with it, good router...wait to buy one of these until they improve on it significantly. What a waste of money.
