I have an Ecotank and my parents have one too (data set size of 2 :). I've had it for 4-5 years now and it's superb for my simple use case (occasional low cost printing at home).
I did initially run into clogged heads too, until I scheduled a test print every month which uses all colors. That way no single color stays unused for too long, and it's been working like a charm ever since.
If the heads are already "degraded" there are two (or more?) cleaning programs available from within the official printer driver settings dialog. They did resolve my initial issues.
Epson could definitely do a better job of informing users though by slapping a big warning on the thing saying "you need to print something every X days to avoid issues".
