Perfect quality for low price

We purchased it for our daughter to use at school. She was satisfied with functions and likes hiw it looks like. There's still a lot to learn about this though. Calculator is much cheaper than the same models from other brands. I highly recommend it

My 12 year old figured out by himself how to use the graphing function. He has Desmos on his laptop, but he needed a traditional calculator for an exam.

My daughter found the transition from her scientific calculator to this graphing calculator to be seamless. The buttons were identical, with the happy addition of on "off" button -- important since it's battery operated!
