In among all the other crazy, Joy's mini food processor died.
So, order another one from Amazon, reasonably cheap and with next-day delivery. The old one was long since discontinued, but its successor is a tad larger and somewhat more featureful.
On unboxing, it turns out to have the new feature of bits locking together: the bowl locks to the base, and the lid locks to the bowl.
Rather counterintuitively, one turns the lid or bowl clockwise to open. What for they used left-hand interrupted threads? Was it made in Australia or something?
Ah... looking at where the sharp bits are, the whirly-go-chopper must run counterclockwise. Ergo, the bowl must needs be counterclockwise-to-tighten.
From a user-experience perspective, wouldn't it make sense to have it open with a standard unscrewing motion, and reverse the blades and motor accordingly?
(It doesn't help that, as received, the locking bits were very tight, so application of a reasonable amount of force in either direction failed to budge either bowl or lid. It took an unreasonable amount of force to unlock it the first time, and a few lock/unlock cycles to wear it in so just a little force will get 'er done.)
