I have/had an original VP one which it wasn't called, and a few years ago the temp/humidity bit the dust, but the solar and wind and barometer continue to work. The Anemometer then got tired and squeeky, and a nearby lightning stroke sort of took it out. How long ago, maybe I got it early 2000s, but since then there are reports of less robust stuff.
I have a few Heathkit 4001 and 5001 s that have been retired due to issues, but the old 4001 a friend has is still working. Is that late 1990s?
Texas Weather Instruments, four of them running just fine, with the issue of maintaining humidity sensors, but there are work arounds for those if you want. One is certainly 20 years old.
Peet Brothers is another I've had excellent luck with the original which I got at Dayton Hamvention, again an ancient station. Just recently a storm broke the wind direction indicator, but after all that time in the hot sun year after year, I can't complain, but cannot climb up to replace the sensor myself and finding a climber nowadays is hard. That station is again over 15 years old.
And the RM Young stuff just keeps chugging along. Well over a decade old, maybe some parts even 15 years.
Maybe I'm just lucky.
