Query: Works pretty well

My house always seems to present problems to wifi routers, and I have tried a few different antennas. This one did increase the signal in a remote bedroom from "good" to "very good" (although not "excellent") on a consistent basis, and I consider that to be a success--and a better result than the other antennas I tried. I did have to fool around with the placement of this antenna to get the best results. For me, I got the best result laying the antenna down horizontally rather than orienting it vertically for some reason.
