Whats the real-world MTBF (mean time between failures) for the Pioneer Pedaling Dynamics power meter? Ive seen the specs claiming IP66/IP67 waterproofing and a 2-year warranty, but lets cut through the marketing fluff. How many actual miles can we expect from this thing before it starts spitting out wonky data or flat-out dies on us? Ive heard rumors of dodgy batch runs and questionable QA from some users, but I want to get to the bottom of this. Has anyone out there pushed one of these units to the limit, and if so, what kind of reliability can we really expect? Are we talking 10,000 miles of trouble-free use or 1,000 miles of babying it before it becomes a paperweight? Im not asking about the accuracy of the power data itself, Im asking about the physical durability of the unit. Can it withstand the rough-and-tumble world of road racing, crits, and rainy-day commutes? Inquiring minds want to know.
