No. That's not what I said.
I said the detents *disappeared*. I tested every single one of the 20 or
so I got, to get a feel for whether there was noticeable variation in
"hardness" of the clicks, it seemed a pretty harsh model, not very
pleasant feel moving them.
Those are the only encoders of this larger category (e.g. illuminated)
that I *ever* obtained, confusing them with other purchases absolutely
And after 2..3 years or so in the shelf, I checked every single one of
them again, and every single one of them had 1) no detent whatsoever,
but 2) also one of the outputs did not have a proper signal, i.e. they
were electromechanically *broken*, unusable as an encoder.
Find it unbelieveable if you like, but that's what happened.
