window vent shades

[Plumcrazzy]

Hello all: Considering a set of vent shades for my 2019 pickup. Anyone have experience with the type that installs inside the window channel? I have mounted others before but have always used the type that uses 3M type tape and mounts to the door frame. Had a fella tell me that the inside the channel type can create an obstruction for the window glass. Comments?
