I had been looking for some blackout curtains for our bedroom window that faces east and couldn't seem to find anything that appealed or in the size I needed.  I stumbled across these liners and was thrilled that I could use them with any set of curtains.  I just hung my new curtains and liners up yesterday and the liners make a HUGE difference in blocking the sunlight!  Other than a little light coming in from the sides and top of the curtains, the room is really dark and I purchased them mainly to help control the heat.  Arizona summers can be brutal and I'm hoping these liners will help reduce the amount of heat coming from the window.  Overall I'm very pleased with my purchase and wish I would have stumbled across these sooner, it would have saved me a lot of time in picking out some new curtains for my bedroom.  I got them on sale too, so they were a Fantastic Deal in comparison to what the competitors are charging!

Pros: Definitely blackout panels, easy to hang
Cons: None
