Q: How well does it hold up in the Phoenix,Az. summer sun and extream heat?
A: In St GEORGE Utah - did not last the summer. Sun almost destroyed the shade.
A: I live in Parker AZ and the mesh part last longer than the edging. The edge turns to dust and very bad the breath in. Almost landed in the hospital.
A: Horribly, I live in a Phoenix and have had the shades for 2 months. They are disintegrating already.
