Do you have any virtual guns?
Its like most things, in its day it probably was good, most here would say the same about the panels we installed 15 years ago. But its tech, and its been switched on for a long time, the longer its on the more warn out its getting.
Most of us here have been installing for more years than that panel has been around, and from experience we can say that it will go wrong sooner or later. None of us have a crystal ball, but we all have experience of elderly panels failing at silly o clock in the morning or the day before someone wants to go on holiday.
You could just wait till it goes wrong, and hope it fails at a convenient time. Or you could take the advice of experience and plan ahead. Its up to you we dont care either way. If you do decide to upgrade you will benefit from better features like fobs, smart-phone apps, better energy rating, (the panel is using electricity 24/7 old transformers are not as energy efficient as the latest switchmode psu's) and ultimately less false alarms.
