No, and never had one of them.

@jebem, I don't know if those VFDs tend to fail; Mine (other calculators) all still work after decades. One of those sellers displays the VFDs of the respective calculators and they appear of equal brighness. Feedback is ok. And yes, the keys have a terrible feel, but at least mine surprisingly never had a problem concerning registering entries. But my only true complaint about the MK-52 is speed. It was the slowest calculator I ever had.
