The calculator is very pretty! and I love it. I chose this colour over the other options as I thought it would brighten up my desk a little. It is powered by a combination of solar and an internal battery that we cannot change! This has disappointed me somewhat as your only option when the internal battery dies is to send it to an authorised Casio dealer? I can't see me bothering to have to pay to send this off (as none near me) just to get a battery fitted, so that tells me that when the battery dies it will be useless to me. Mmmm. That point alone made me want to give it just 1 star rating, but that wouldn't be fair as the calculator is gorgeous, easy to use large keys, all the functions a normal person would require and even a % button (which is why I chose this particular model) The price I paid represents good value for money for what it is, however, I feel it is let down by the fact that you cannot install your own new battery when this one dies! That displeases me a lot and I think when it does die, rather than pay posting and suffer all the faffing about sending it to an authorised dealer would cause, I think I'll just take a screwdriver to it myself and see if I can fit a new battery myself. NO idea how long the battery will last. It has auto shut-off 5 minutes after last use (cannot turn it off yourself) and there is the solar power element - trouble is my desk has no sunshine falling onto it, so no idea how the solar power thing is gonna work for me.
Overall I am delighted with it, apart from the niggle with not being able to install my own new battery when this one dies. Looks great on my desk!
