I have always used AVS in-channel in the past, but I had a problem with rear ones falling out on my Yukon. The rear window on my truck is a lot longer than the Yukon window and there are a lot of bad reviews for the same thing. I prefer the look of the AVS on the front window because it doesn't run down the front side of the window, but I'm done dealing with trying to keep the rears from falling out. I have actually bought and installed the weathertech brand on my truck. I'm happy with their quality so far. I too read the same reviews about weathertechs, but I decided to give them a try since they had the clips for the rears. The clips are little bit of a PITA, but seem to be pretty effective if someone takes their time and installs everything correctly. IMO, the folks having problems with the rear weathertechs aren't installing them correctly.
