Great calculator for engineering.
J. Sacher✓ Verified Purchase•November 30, 2023
Love the engineering entry with M, K, n, p, u. Keeps from screwing up a calculation when you use the wrong power of ten modifier for micro, nano, pico, etc. It is typical the small inductors and capacitors that mess me up.
Excellent value

I am a bit of a calculator hoarder and this is one of the best values I have found. While I usually focus on HP RPN calculators, sometimes it is nice to have something more simple around. This calculator meets all of my calculation needs, is fairly rugged, has an extensive built in constant library and even features approximations to integrals and derivatives. All in all an excellent buy.
Always love this calculator

Always love this calculator. I used it when I was in school. My sister was looking for one and couldn't understand some of the scientific calculator functions. So I bought this and there you go... yaaahooooo.. she loved it ðŸ˜ðŸ˜

The product seems to work fine but the packaging was all cut open.
