It would last many years to come i'm sure, but i think it's a bit too small considering they spend up to 5-8h a day in it and are very active. I'm in the process of constructing a new bird room which will give them a bit more space to move around in.
So yeah, the main reason i get rid of cages isn't usually that they're falling apart, it's mostly because i'm building something new.
This is a picture from when i just got their current cage, ie it has neither branches, enrichment nor birds in it.
Great cage though, i'll probably keep it just in case.
