Query: Worked well for me

I haven't had any problems with my device, maybe mine is newer than the others that have been reviewed. Also, I do not have wireless access at home, I just use it at college and at other businesses with wi-fi. I have used it for hours at a time with no problems at all. I only sold it because I got a cell phone that can function as a wi-fi adapter. My only complaint with the Buffalo adapter is that it does stick out about 4 inches which can be awkward at school or at a restaurant table.
