No one ever really answered this, so I'll chime in. I ordered 7 chromium steel pinballs from Titan for my Tommy machine and they're fantastic. I haven't tried SilverJets, but I would guess these are close in quality (for a much cheaper price). They are just as shiny (if not shinier) than Pinball Life's premium gloss balls and they play as smooth as you'd expect. Note that they have a protective coating when you receive them and may be dull and dark looking - once you clean them off they look incredible. I'd definitely order these again and, as everyone has said, Titan has top-notch customer service.
