I always wanted an air compressor but could never justify the expense nor the space it takes up since I have no air tools and don't really need air tools. But I inherited my dad's compressor now and I went online to find out how to use them and came across all these videos talking about air compressors exploding. Apparently the inside of the tank rusts and weakens the metal after a few years. You can slow this process down by draining the compressed air after each use. But I have no idea if my dad was in the habit of doing this. His compressor is from 1999. Appears to be in good shape so I don't think it was used much but I wonder if it's worth the risk.
