I have the slimmer version and think they are the nuts
I did find though when fitting the holding clips if not lined up properly the windows will want to return to open when trying to close!
I wouldn't be without them they seem a natural part of the van.
I was initially going to get the sleek ones, but decided to go for a little more coverage so bought the retro. They are still pretty low profile, I was expecting them to flare out more being called retro but I am really happy with the look.
Agree with others, they are a doddle to fit, takes longer to take the protective plastic off
Also very handy towards ventilation issues
The windows can be lowered a couple of inches without noticing they are open from the outside,which I do when sleeping in the van and knowing if rains all is Ok
