Every issue I've seen others have has been user error or lack of maintenance. And there are only 3 moving parts, that even then, move very little and very slowly, not much to break or fail. Nutrient caused clogs are the most likely issue. I keep a spare tubing assembly that I swap out monthly, then I clean the one removed by flushing it using a 30ml syringe. I've been using my pots 2 years now and have had no issues at all. Chances of mechanical failure are very low. 99% op error IMO.
