Very easy to install.  My husband and I measured them together, I would recommend you have someone help you measure and cut, especially if they are going to be long. We also put an additional strip of trim up to cover the track since our trim and the panels were a darker color, the track kind of screamed at us. They look great! 

Pros: Great value, good quality.
Cons: The track really stands out if you have a dark color panel and trim.  Wish they had a way to close so you didn't have to always touch the actual panel to open and close.
