I've never understood how those are able to work well enough to keep selling.
Best I can tell, they have to go on the outside face of the dropout. Which would make the caliper position dependent on DO thickness. But calipers and rotors take their reference off the inside face. And caliper sideways adjustability isn't that big.
Is there really that little spread in DO thickness?
