Doesn’t work
It wouldn’t turn on when I got it. I opened it up (it has tiny little screws so I’m shocked I was able to find something in my apartment small enough to open up the battery compartment thing) it has batteries in it already so I flipped them every which way and it still wouldn’t turn on. It might just be the batteries because one of them is a bit rusty but now I’m trying to figure out if it would be worth it to get new batteries or if I should just order a different calculator.

Cheap with many functions, but LCD display has serious viewing angle problems
This calculator has some good things, most notably the low price and a great number of mathematical functions, but there are some significant problems with it. I found that, once getting used to the numeric entry of various functions such as y^x or using pi in an equation, it was easier to use, but I’ll have to admit I’m a fan of RPN from my HP calculator days and prefer it to standard entry. The worst problem with this calculator, and the greatest hindrance for it being useful for much of anything is the terrible viewing angle characteristics of the LCD display. If I place this calculator at the usual place I would use my phone or a better quality calculator, the LCD display is unreadable, and this makes this item rather hard to use, and more of a novelty than a real help to students or engineers or whoever else might want the functionality of this product. If I had to grade it, this calculator would get a ‘C’, only because the price is cheap.

Mr. Pen Scientific Calculator for my daughter, and she loves it. It’s an excellent value for the price, performing all necessary functions without any issues. Compared to other, more expensive calculators I’ve used, this one holds up just as well, if not better. It’s perfect for students and a great tool for math, engineering, and other academic needs. Definitely worth the money!
