problem with the bitspower ones just like the black bp fittings, if you just hand tighten everything its fine, but i like to use a set of mole grips just for that extra 1/4 turn just to be safe and the problem with that is the scratch real easy, so your left with unsightly exposed brass, I'd buy any cheap fitting and paint them tbh.
You get the colour you want and as long as you mask the inside and the g1/4 thread you can clear lacquer coat them so they wont scratch up so easily.
