To repeat my views of the company and the grinder for the umpteenth time:
-- My views of Versalab, the company, are based on what they told me when I had problems with the grinder. They said I had voided the warranty by using it for cupping and by grinding too lightly roasted coffee. Then they "graciously" offered to nevertheless refurbish the grinder for free, provided I posted nice things about them. This did not strike me as gracious, but as deeply insulting, and bordering on blackmail and fraud. My audiophile friends tell me incidents of publicly critical owners being blamed for equipment problems and having their warranties voided were also quite common when Versalab was producing a well regarded but controversial tone arm in the 1980s
-- My view of the grinder is based on professional and engineering opinions on its long term viability as a lab and cupping grinder (the major reason I bought it, as I told John Bicht). In their unanimous opinion, for this use, and for overall commercial viability, the unkeyed friction fits between the pulley, the drive wheels, and axle, along with the single bearing suspension of the axle so far from the burr, are flaws. I disregarded their input; but after six months, the belt and drive wheel started slipping, and after a year the bearing was shot. So their prediction about the grinder's weaknesses were borne out. In their opinion, the grinder is an excellent piece of design that cannot be made reliable without being revised by a competent production engineer.
As you can see from this account, I have excellent reasons to both doubt those singing the grinder's praises, and to repeat my experience whenever the events underlying my judgments are distorted.
