The Nubbin is one quick little adapter if you can keep it within about 15 feet of your access point. It simply outruns the other adapters I have on hand. The price is good for what you get and the software that comes with it is excellent. It is a great adapter if you do not have an N adapter in your notebook or netbook already, or have limited area to work with.
I would not recommend this adapter if you are looking to use it at long ranges or you have a weak signal in your house. I also had an issue with the Nubbin getting lost in my laptop bag due to its size. This is not something that cannot be overcome, but it is an issue to be aware of.
With that all said and done, the MvixUSA Nubbin is still a good pick up for the right kind of user.
