A neighbor gave us one when he moved up to an HP-25 (lower number, but a later and better calculator). I used it in college. I remember running across campus on my way to a chemistry test, playing catch with my calculator (in the padded case) as I ran. I had confidence that, even if I dropped it, it would still work.

I accidentally sat on my HP-15C in college and broke the LCD. I wrote to HP to see where I could get the LCD replaced. I was a college student and the thing was like $125 1986 dollars, I wanted to fix it, not buy a new one.

They just sent me a new calculator for free. I was so amazed! Heh.

I repeated almost the same accident with an early kindle and Amazon did the same free replacement. I don't think they do today.
