I have never seen one so can't comment on how well it works but if done properly it should be reasonably solid and agile.  I think the guy who designed it also sells them commercially but from what I can see the design is also available for others to use.

I bought one of these  three  years ago. It is very reliable and the perf is very good. I attach a couple of shots from this morning. 



It does not unfortunately propagate the leap second status. But as I use the NIST files that is not a problem.
