I've had a PFP5 for a few months and so far I'm pleased. I don't use ultra-high pressure (only 100 lbs), but at least it's not leaking like my old cheap Zefal did after I got off the fat 26" tires. In general it would be nice to have more metal and less plastic in the pump, but that's nothing specific to the PFP5. I like the large dial and the chuck / finger latch design seems to work very well.
