Summary: This item works great! I have used wireless cards and small USB adapters in the past but have always had issues with getting a signal if the router is on one floor and my desktop is on another. This item is powerful and able to pick up the wireless signal clearly and gives me the speeds close to what I'm paying for (upwards of 25 mbps) as opposed to what I was getting before (< 3 mbps).
Summary: Yes, it did improve the reception somewhat...but NOT to the extent they advertise by a long shot. I guess they claim it "could" increase receiving and sending signal strength by"up to" 10 times more. I found that even at shorter distances of less than 300 feet, I only went from one bar to three bars, and not much in the way between it and the signal.
Summary: I have been trying to pick up the signal from router in the house next door(the parsonage, want to get internet at church) and this is the only adapter that I tried that was able too!! Even get full signal strength!! The other ones I tried that didn't work cost twice as much. I may buy another one as a spare since it is so cheep.
