Difference between Prius Heat Shield and regular sun shields?

I suspect you'll have a hard time finding one to fit the Prius windshield exactly at your local K-Mart or auto parts store. They're either too short for the Prius' long windshield or too wide. The wide one (more suitable for large pickups or SUVs) will work but they're cumbersome to use. The Canvasworks shade is made to fit the Prius.

The Canvasworks shades rolls up for storage, rather than accordion-folding like most. Some think it's a PITA to roll up, but it doesn't bother me.

The Canvasworks shade will sag somewhat in the middle after awhile. It hasn't been a big issue for me, but it has for others. Another PC member, efusco, described and posted pics of a modification to the shade that solved the sagging problem. Sorry, I don't have the link, but you can try searching, or maybe he'll see this and post.

I used an auto parts store model at first. See this thread for a problem with the dash display that arose after using it.

Here are the pictures that JimboK is referring to. OK, it's a bunch a pictures, but you'll be able to find to relevant ones. I did the same thing with my shade (following efusco's pictures) and can attest to it working. I get little to no sagging. And the best part, when my wife saw what I was doing, she thought I was brilliant! I did give credit where it was due though.
