exact ones i got.
i was expecting plastic.. but they are like pseudo plastic stuff. (they say pvc) it looks like its really easy to work with, but i will have to take a dremel to it. the baskets on these beasts are a little bigger on the inside then the adapter has room for.
but they look like they will stand out far enough so i won't have magnet vs window issues.
