I bought this for my child's geometry class. It arrived in a couple of days and worked well right out of the package. Half of the school year has passed and it is still going strong. It's not too large, so it fits snuggly in her backpack. Like most scientific calculators, it came with a cover to help protect the buttons. Overall, it works as intended and I would happily purchase it again!
