Living in Arizona I have experience with almost every style and brand of sun visor. From folding fabric, plain cardboard to insulated reflective folding panels. My last sun visor was the WeatherTech, which is similar in price to the Covercraft and quite good. However, I've never seen a temperature difference nearby with my Covercraft. It is very well made and fits like a glove. In the Phoenix summer months, it's worth every penny.
