Reviewed on 2008-04-09 Great Calculator This calculator is perfect for an electronics tech. The metric symblols (T,G,M,k,m,u,n,p,f)let you easily enter engeneering notation for quick calculations. I have not seen this feature on any other calculator, so I bought myself a backup!

Reviewed on 2008-04-08 Very nice I've been addicted to my TI-89 platinum since I got it. However, this is an excellent substitute for when I can't have it. All I have to say is that this is by far the best calculator for the FE exam. (Make sure yours is solar powered.)

Reviewed on 2008-02-18 Casio for FE Exam This calculator has so many functions to use that will be useful in the FE Exam, however, it becomes really difficult to figure out how to use these functions. One thing I found is that you cannot convert decimal to fraction while in engineering mode. Other than that, it is very useful.

Reviewed on 2008-02-07 Good, full-featured but a little short. . . I bought the 115es originally, and for some reason, NCEES disallowed it from the FS/FE exams, so i also got the 115ms. Note, NCEES appears to be allowing the es again; the approved Casio model has to be a FX-115 model, no designation as to it having to be the ms. So the ms is very nice! Very clear, crisp display, intuitive keyboard, these things being better than the es. The ms is also full-featured, having solve & calc functions (very handy), ability to do derivatives, integrals, quad & cubic equations, solve simult equations of up to 3 unknowns, full statistics capability, etc. But the ms will basically be relegated to being my backup to the 115es, because the es does everything the ms does, and has unit conversions, scientific contants, matrix, table, and vector capability; in addition to being more user-friendly in toggling between the desired mode of operation or setup style. I'm really not sure why Casio offers 2 such similar platforms, separated by a minimal price. . . i mean for the money, why wouldn't you get the 115es? Hopefully, NCEES will not exclude the es from its approved list again (totally don't know why they did in the first place). But comparing either casio model to the approved texas instruments models, or the HP models, the casios offer great value & practicality, without a huge learning curve. If you're not remotely concerned w/ any of this NCEES speak (i don't blame you), buck up to the 115es. For a few $$ more than the ms, it provides a lot more features.

Reviewed on 2007-11-23 Excellent functionality and ease of use for a great price This calculator was recommend for an AC Physics course I'm taking and it is a great deal. Two things that are particularly great about this calculator are that you can enter scientific notation prefixs (p for pico, n for nano, etc.) so you don't have to do the conversions in your head. Another highly useful aspect for electrical and engineering applications is the ease with which you can enter polar and rectangular coordinates. For most calculators I've owned they either lacked the feature entirely (it is rare to find polar and rectangular support in calculators at this price range) or were extremely clumsy to enter and use. It also appears to do differentiation and integration (a surpise for such an inexpensive calculator) but I haven't had need for those in my current courses so can't say how well it does them.
