MP ConceptsQuarter Window Louvers; Gloss Black Compatible for 15-23 Mustang Fastback

Meh...not very impressed. Consider the rating as 2-1/2 stars.I got the package and opened it up but was kind of disappointed to find the louvers weren't open and it was just a piece of molded plastic probably costing a couple bucks to make, not true louvers. I had gathered from the pictures that they were open.Anyway, I went ahead and installed them using the tape and accelerator that came in the package. Word of caution: Try to stretch the tape out when you attach it to the louver or you won't have enough. They sure didn't spare any extra tape!A couple of weeks later, I noticed that the driver side one was loose. I pressed it back on but it came loose again. For fear of losing it, I removed it and ordered more tape on Amazon.So, we'll see how the reapplication goes. Down the road, I may remove them completely as they are kind of cheesy looking on my new 2020 Mustang.
