I purchased Clear TV from Kmart, and it contained holes for attaching to the wall, as well as suction cups for attaching to a window. It also has a long cord. I chose to use the included screws and attached it high up on the wall. I scanned for channels and picked up 49 digital channels. Four of them don't pick up too good, and go in and out, but the rest are great and very clear.
I went back to Kmart and purchased two more and installed them on the same way for two additional TVs. They also work great. One of those picked up 51 channels (5 of which are not so clear but I wouldn't normally watch anyway), and the other picked up 47 channels (3 have bad signals). Of course, I canceled Verizon FiOS and am extremely satisfied with Clear TV. I no longer am being cheated by paying cable subscription fees for commercial filled channels.
Bottom Line: Yes, I would recommend this to a friend
