I’ve just been using 89s since I was in middle school. Always liked them. Always kept with them. My main calculator is a 20 year old 89 Titanium. Those things are built like tanks.
Though it may be a bit of a ship of Theseus. I’ve replaced the cover and battery cover 2-3 times, and I even replaced the tiny backup battery cover once.
