Thank you so much for the feedback!
Chas,
I have these. I made the mistake of not adding extra 3M tape (highly recommend!) - only put them on with what they came with, and one (rear passenger) came off a month or two later because my 9-year old uses that door. Others are ok but maybe that's because I am careful not to step on it and I rarely have front passengers. They do "curl over" and it looks nice; I have not noticed any door seal interference. Hope this helps!
