The actual oiling didn't take too long, it was just finding the time to do it, and not too close to a game so that the chips would have time to dry. It always seemed that when I had time, it would be 2/3 days before a game, so they never got oiled in case they were a bit oily when the cards started flying.
Overall yes I've done well playing with them, but I generally use them in very social games where the beer flows - and the only donks are drunk donks, which is convenient! The chips are used every 5 weeks and every so often have an extra outing.
