If you had one delivered to your door today, what on your bench would you
replace with it?
A lot of what it does is not "as good as" a $30 e-place DOCXO. Other than
power / weight / size, you can significantly beat it today with a sub $100
Rb from the same sources. For stationary time nut in the basement stuff,
it's tough to find a place for it.
That said, it's a very cool little gizmo. If you do need low power / tight
accuracy it's going to be hard to beat. It's certainly a good part for
portable applications. Packing around enough battery to run a 10 W Rb for a
few days isn't very practical. Running one of these off a couple of lithium
cells would work pretty well.

Wonder what the lifetime is?
Surely for time nuts they will have a special deal. Like $199 for today
Well we might dream.
