Great at heat management, not the most forgiving to install.
Great in terms of heat rejection. Made a solid difference in cabin temps. However, even on a alcohol cleaned, smooth metal surface, the existing adhesive backing did not adhere completely. Could make it difficult to install in certain circumstances. Otherwise, good product!
