FWIW, the AVS in channel ones I installed last week or so are still on there. The weatherstripping has settled down around where you install them and looks much better. (I'm sure being in warm FL helps this. I wouldn't want to install them in NY in January

). To date i've had no issues with the windows sticking, auto-retracting, anything. I just wish they would stick out juuuuust a little farther like the external mount. They do look much better, though

.
