I have had the same exact issue with these AVS in channel visors. It has tape on the inside to stick into the window channel. The funny thing is, since it doesn't really stick properly, you need to find a way to hold it there and bring the window up to help it stick while not chopping off your fingers. I didn't like these at all. For one, like I mentioned they didn't really stick. Two, I didn't like how the window and the visor were competing for space inside the window channel. I felt like the window would eventually go out of alignment. I ended up returning them to Amazon (where I bought them). I haven't bought new ones yet, but if I do, they will be the ones that go on the outside.
