We have had our Lexor with Winegard for only about a month but have tried it in a few places and LOVE it. You can't get easier- just turn it on and push the scan button and it does all the work, then tells you how many channels it found. Then, you tell your TV to auto scan and in about 5 minutes, they all tune in.
Of course, metropolitan areas will find MANY channels, but other remote places, there may be no signal. This is our first experience with any RV or antenna system so we have nothing to compare it to but for newbies, we are very happy with it!
