Let's put things into perspective. We're talking about the pinnacle of an intensively competitive market, with lots of compelling products. There is some level of product differentiation butr not enough to greatly affect consumer choices. Up to some point, demand is also generally inelastic relative to pricing. As far as brand loyalty, D-Tek is not a newcomer to the industry, but its claim to fame is a relatively new event. I guess there is little to no brand loyalty among hardware enthusiasts, I guess besides me lol

On a 50 degree base load temp, a 3 C difference is the equivalent of a 6% absolute improvement, and who know how much when comparing block relative to block. A 5 C load difference, if attainable, is the same as a bases-loaded home run as far as I'm concerned.

So far, I'm not seeing 5 C differences but I am definitely seeing 3C differences, noting that the D-Tek FuZion and the Apogee GT are basically on par with each other.
