i had 2 different brands on different trucks and heres my imput. the avs in channel are decent. like the op above me said they do offer a little resistance when rolling up the window but i never had issues with them. they did have some tape on them to stick to the inside of the track which held it firm. i also had egr in channel and while they looked good also they had no tape on them to stick inside the window track. if you left window down and shut door theyd rattle not while driving but just when shutting door. other than that they were fine too .
