With the word "budget" in its descriptor, there are bound to be some drawbacks. Functionally, there's nothing wrong with the TI-30XA. It's undergone multiple revisions since its first release in 1996, and I'd assume it keeps getting better with each one. However, until 2013, this calculator had a small bug that resulted in slightly inaccurate calculations. Rather than explain it and take credit for someone else's work, I'm linking to another calculator website that's much better than mine if you're interested in learning about it: http://www.datamath.org/Story/LogarithmBug.htm

Again, the TI-30XA is a good calculator. You can get the latest revision for about $9 on Amazon or the solar version for $14. I see them at Goodwill all the time, and people send me pictures of theirs more often than any other device. I don't know how many times people have asked if I have one, but maybe this review will put that question to rest once and for all.
