Title: Slow, slow, and slow.
Review: This calculator came days past its already distantly-predicted delivery date. I needed it for class and ordered it in plenty of time and didn't receive it until I had already gone without it in multiple class times. When I finally received it, the screen had black digital marks on it that have faded some now but still reappear at the slightest touch. Overall I am not happy.
