When it comes with the same sheet of paper it is as useful as the "old" one..

And as long as they would use the same reference IC nothing great will change, maybe the stability but this you can check with a period calibration, regardless if new or old version.
do you really benefit from spending more money on calibration?
When I want to know if it´s "true", it should be worth the money.
My skepticism started when I realized that the components on the L/C board are not high accuracy types, but only those that were measured with their LCR meters.
Then most of the values are rounded.
It may be that I am "damaged" by my profession in this respect, but if it is advertised that it should be a device for the calibration of other devices, then it should also be documented extensively.
