Build Quality of Graphing Calcs & Others

[Quadratica]

I've been using a TI-nspire CAS for 3-5 hours every week since I bought it in Sept 2011. It still has the same battery which holds a charge for ~2 weeks. The body of the calc has a few chips/scuffs, all the rubber feet have disappeared, the screen has a scuff due to my recklessness. However, it works perfectly and does everything I need it to do.

I bought it for about £100 in Sept 2011 and 12 years later it still serves me well, I think I got my money's worth !!
