Sometimes the best things don’t need to be modern
I have used this calculator since I was a kid. It’s perfect and never needs an update!

Sturdy, functional, and durable!
I first bought this calculator new in February 2018 (for $113) and it has held up well to this day! It arrived undamaged and on time thanks to seller “Excellent Products Inc” with the corresponding cables and manuals, spare batteries and thanks. I then used it almost daily for school and homework up until about two years ago (before taking a break) and have never even changed the batteries. I kept it in the upper compartments of my backpack and sandwiched it between other items to further stabilize it, and besides the occasional scratch along the back, it still works perfectly and looks as though it will remain the same for years to come. I felt it was sold at a great price and worked well through several math/math-related classes including finance, engineering and computer science. Overall although I cannot comment on used devices, I would highly recommend buying similarly new calculators for responsible students in middle, high school, college and beyond; for all this and more, I give the TI-84 Plus (and the aforementioned seller) a respectable 4/5!
