Love that thing. Have one in a box for when I set up my bigger tankI have been running an Avast Marine Plank auto feeder ~3 times/day with their reef jerky, I sprinkle in small amounts of flakes occssionally and some frozen mysis in the evenings. I try to do a little, more often, rather than a lot, less often..
The Plank Feeder is a nice little unit, but spendy. Requires external timer control, I use a Kasa smart plug. I do have to clean it regularly in the DT as it can get clogged with algae fairly easily, would love to have a sump the throw it in the return chamber..
Auto feeders & auto top offs are my favorite things..
