This is a fine calculator. It works great. Has more functions than I'll probably ever use. Then why do I not recommend it?
There is a design flaw.
I have attached 3 photos where you see the screen. You'll notice that when you turn the calculator on and look at it from an angle (as you would if you kept it on a desk while you were testing) the numbers are not legible. Your line of sight has to be almost perpendicular or direct to see it clearly. This does not affect the function of the calculator but it gets inconvenient when you have to hover over the calculator or lift it up to read it. In a test taking setting this constant movement was suspicious enough to warrant a warning from the proctor.

Changed signs.
By Robert B. Langston on March 4, 2020
I have a very TI-30X solar calculator that has served me well for many years. The buttons are starting to act up a bit and my daughter needed one for college, so I ordered her this one. My biggest complaint is why TI chose to change some of the symbols for the functions on the machine from what they have been for years. I.e., 1/x symbol is now X-1? and the square root has been moved back to 2nd function when it used to be a primary function. Its a pain since you used the square root function all the time. A bit nit picky, but they messed up a really good designed calculator. I do like the fact that it now inputs formulas that you can see on the screen. But why mess with the keyboard and make it less user friendly.
