I have one. It's fine as a break cue. Simple and cheap. I don't think it's a great jump cue, to be honest...or I should say there are better ones, anyhow. As far as breaking, it breaks about as well as any other break cue, best I can tell.
Personally, I don't really care for the 13.25mm tip, though it doesn't really bug me either. I'd prefer a 13mm.
