But does it actually work? 
I tested many cheap wifi adapters.
Often these are packed with either a ralink cheapset(RT3070) or a RTL (8171(L)) or similar.
They are not that bad perse and often are 'powerfull' however sensitivity is just as important, its useless to shout when you cant hear.
Main problem with crap built adapters is stability, connections are often sloppy, high package loss, random drops etc.
Ever since alfa and a couple others start building these things the market is flooded with 5000MW WIRELESS ADAPTER SUPPORTS HACKING!
If I want true wattage Ill just redesign my microwave at home ? I would have 800Watts, now thats powerfull!
