My previous Casio calculator developed a print problem after many years of use. Having used this new CASIO FR620TEC print calculator for a few weeks, I would say this machine is an improvement over its predecessor. The auto power save function came as a surprise and took some getting used to, but I guess it's driven by ECO directives from on high. The paper tear-off appears much cleaner then previously although this may be because the machine is new. There are many features which I'm not likely to use, but it's good to know they are there in case of need.
If this calculator has the longevity of my previous machines then I will be more than happy with this purchase.
