You can go find his posts on this forum. He “upgrades” the common points of failure with better components, which he explains at length. Don’t need to prove my point with semantics as this is not an electrical engineering forum. The large amount of failures on the EB832 prove that point."Sturdy" is a meaningless adjective when describing electrical circuits. "Fail-safe" is near impossible to determine without having schematics (from manufacturer or reverse engineered).
