I've been using the ecoflow system for a couple years now. Like anything that is using technology, it's great when it's working. I've only had a couple of hiccups that was mostly my fault. But like always two is one and one is none. I also have multiple generators that run on lp and gasoline. A solar generator is a very useful thing. Power on demand and quiet, but also limited. I just happen to like the ecoflow stuff.
