Can't comment on the fog versions, but if the output & beam focus is anything like my non-FF driving beams, I'd opt for something else. There's a guy on eBay selling the compact 100 clear fogs for < $100/pair including bulbs & wiring. At that price, Ive been considering putting a set on my work truck, but don't really need them as the factory Hella fogs work just fine.
For reference, the Compact 100 driving lights with Narva bulbs and shipping cost me nearly twice that amount (not including switch & wiring)
