They do look good, but I am very skeptical about how he claims it reduces brake caliper heat. He is not comparing apples to apples. On one side he is measuring the actual calper, the other side he only measuring the temperature of the cover. The cover is nothing more than a shield, which will not get as hot as the caliper. I wouldn't be suprised if the actual caliper could be getting hotter since it is not getting the air circulation. Until he measures the actual caliper under the cover, I don't buy it.

Maybe he should have compared and showed us the difference in temperature of the rotors if the covers are so effective.
