I’ve looked at these a few times over the last couple of years, and they’ve always peeked my interest, but it was always when I was on another mission.

Needless to say, I never bought any.

Looks like a reasonably inexpensive way of not only maintaining, but obtaining an over the top edge, if one so desires.

A 4K to 600k progression for about $700 is, IMO, pretty good bang for the buck.

Anyone tried them, any feedback?
