Ugh, awful. I use a piece of copper tubing with a cap on one end. I use the un-capped end to tap out the cups / races. The copper isn't hard enough to damage steel. After a while it gets bent over and I use a tubing cutter to cut a cm or so off, then start again. One tube will last years, given how rarely I need it. I didn't invent this method, I learned it from member Grand Bois, on this site.
