I have never had a problem with any of the pipes I have purchased from P&C. I don't know if P&C does any additional QC on the new pipes they sell, or if they simply pass them on as is. Buying a new Grabow in the blister pack is always a crapshoot, because not only can you not closely inspect it first, the dealer can't either, unless they remove it from the blister pack. I have purchased a couple Grabows from them; they were in fine shape and I would buy another from them if I was in the market for one.
