Summary: This is probably a good calculator but mine doesn`t even turn on! Nothing, not even the solar power works.Completely dead. Not recommended. ****UPDATE**** Ok I got a refund from Amazon and purchased another one.
Summary: It's a good basic scientiic calculator, with all the bells and whistles you would expect for the price. I still like my HP 32S2 a lot better, but you can't get them any more. The solar power is a really handy feature.
Summary: I've owned three Texas Instrument calculators in the past several years and all three have died on me. I owned a TI-83+ Silver Edition which failed after only two and a half years (I have never dropped that calculator).
