Flaps don't work at all. The other works fairly well on a flat or slightly curved surface with a slight angle. It held my phone up to the car's dashboard, which is curved and doesn't have flat areas good enough for me to see when using the Maps app. I've never left it on the dashboard in the hot sun so no problem with it melting or anything. I've left it in the car in 90+ degrees and it hasn't melted or left residue when I moved it. I liked it so much that I bought it again, but not foldable. If I could only find a flat I would buy again.
