Can't afford that
The most.expensive ESC I own is a xr10 Pro legacy
For a normal club racer for me, that ESC is not needed.
If I were a pro with sponsorships. Sure I'll take it any day.
It wouldn't be great for it but if they have it shielded properly it shouldn't be too much of an issue I wouldn't think.
My very first thought when I saw this was why put the heat sink on the bottom? After giving it some thought, if engineered properly I would think it will be adequate even if it's not the ideal placement. The fact that they used a composite of aluminum and ceramic for the heat sink will help with the transfer of heat, but I'd personally only use this in a track kit where air flow will always be constant.
