As far as I know it is the cheapest Cs ever produced and it is
specifically targeted at telecoms where no GPS signal is, can
or will be made available.

It's main advantage over rubidium is the lack of drift, so you can
mount it, power it, push the button and as long as the light is lit
(10 years guaranteed) you have a good sync clock for your telco
network.
