Purchased a g'zillion of these for all our windows and love them. Our home is all plaster and lath so holes don't also end up exactly where you want them when drilling for anchors. Smart design saved us! They're flexible enough to tolerate those little inconsistencies and they're strong. Our windows are in sets. The longest rods have 8 panels hanging on the outside part of the rod with no problem at all and the curve at the end is perfect as it allows you to tuck your blackouts so like is actually blacked out!

I'm extremely happy with these. :-)
