Nick Pape: When I was in school they were black. Only black. This is so much easier for my kid to find at the bottom of her school bag and has the same great functionality I expect for a school scientific calculator

O. Long: The school packs come in the dark blue. The red makes them easier to see as you leave competitions and they match our school colors. Overall the calculator works great. The solar power makes it so you don't have to buy coin batteries and this calculator can take a backpack beating. Have bought it several times and given it to kids. Highly recommend for chemistry and physics class so the kids don't get used to the crutch of graphing calculators or the dumb buttons "nsolve".

Katelynn: I'm back in school as a 30 something and needed a scientific calculator for math 107. This has been a great value. So far it's done everything I've hoped it would (Continuous compounding, other financial formulas and finding standard deviation mostly). I suspect it'll do everything I need for this course and beyond considering I'm majoring in psychology and nothing math heavy. I did have to look up video tutorials on how to use it since I found the instruction manual confusing but that's just user error since I've never needed to do much math before.

Jack: Design and Build Quality (5/5):
From the moment I held the TI-30XIIS, it felt like a comfortable handshake with an old friend. Its design is simple yet thoughtful, fitting snugly in my hand.

Functionality (5/5):
This calculator is like a Swiss army knife for mathematics. It covers all the bases, from basic arithmetic to advanced functions like trigonometry and statistics. Its two-line display is a lifesaver, letting me review my calculations step by step. I can't count the number of times that feature saved me from errors.
Ease of Use (5/5):
Whether you're a seasoned math whiz or just starting, the TI-30XIIS welcomes you with open arms. The buttons are laid out logically, and the menu system is as intuitive as a friendly chat. And when I needed help with more complex functions, the included manual was like a patient tutor guiding me through.
Battery Life (5/5):
The calculator's solar-powered heart never fails to amaze me. It slurps up energy from just about any light source, and the...

Helmut H.: It does what it says on the tin. Some operations are a bit complicated. Doing statistics one has to remember that only ca. 49 values are stored! It’s good value for money, though.
