Until a week ago, I have been put him in my education in technical business administration where it was used exsessiv in Accounting and Finance / Investments.
(Why do I no longer use it for a few days or only as a reserve in case of emergency during the test I describe further below)
Expects very quickly come "clearly comfortable light" with which means you must not illuminate him full grenade from above so that he still expects fast and is easy to read.
Keys have a pleasant pressure point and give good feedback. You do not rattle and not wear out (numbers, strings, etc.)
It is robust, and "Splash" insensitive. Some bumps and falls, he had already endure and still does his service. A few days ago he has a neat splash water gotten me as an open bottle of mineral water is upset. This is in the pause happens when leaving the room. Probably someone from the course who overturned them. So the computer has located a few minutes completely wet in a puddle. Had him dry and he works perfectly. Am only afraid that he lets me in a few weeks because of his age and this shower at the closing down. Therefore, I have a few days ago bought a new copy what I use since then. Have to say it is exactly the same as a few years ago. Great tactile feedback of the keys, speed and lighting requirements. Casio has apparently not changed. So I can recommend this product still!
