The clock is built high, thereby very easily. The service is typical Casio. If one has read only once in the bulky, shapeless operating instructions, to get mE with the Casio usual terminology quite well. She is getting used to and you have to really deal with it; but then it goes quite well. I recommend creating your own small short manuals to the most important features that you need.
All functions of the clock in the various modes are working properly. The user interface is quite logical and intuitive - this is of course subjective, but I get along well with them.
Overall it is a nice clock with many features that I would always buy again. Given the very good price-performance ratio, one can even speak of an outstanding purchase. Who likes the clock, get a super time iron, on which he will last a lifetime. I've been buying, as I said, no regrets so far.
