I bought four seemingly identical, cheap Cuisinart burr grinders over a period of 5 years or so. One of them happily endured heavy daily usage for several years at a workplace until it 'disappeared' during a move; I found out years later that the person who took it still had it (no hard feelings! someone told them it was company-owned and being discarded) and it was still working great. Another (a gift) was still working a decade later, last I checked. The next two I bought failed within months. Apparently they made some minor tweaks to the build that completely ruined the durability. I'm sure they sold thousands of those junk heaps on the reputation they previously built.
