Mine will be 11 years old in 6 weeks from now.
Temp/hum and UV sensors were replaced under warranty early on.
Have bought and replaced temp/hum sensor twice since then.
Anemometer failed after 10 years so replaced with new.
FARS complete fan/motor unit replaced once, motor replaced my myself twice. Not bothering with that anymore so just a passive shield now.
All other parts original and working fine including ISS and supercap, but white plastics showing their age for sure.
