Sure. Ymmv. I have pretty good evidence my AquaPure cell is 16 years old, though it was broken for a good fraction of that. I got it working again 3 years ago when we got the house. Some report corrosion problems, but I'm not seeing any of that. It's making exactly the 1.25 lb/day it's rated for. Since I got a VSP and run it 24 hours, the cell does fine most of the time at 10%, sometimes 15% if it's really hot and sunny. I like being able to track and adjust the cell from the same app that controls everything else.
