I've never used it since getting my PPL. That's probably a sad reflection on my part for a number of reasons:
1) I've only landed at places that I obviouslly don't need to worry about it
2) I've almost only flown a PA28 with one passenger
3) 95% of my flying has been in and out of the same place
4) I'm now doing Aero's (see point 3) (not in PA28 either
I doubt I'm the only person like this, but it does come into my mind now and again that I should practise such skills.
