To be honest one of the best parts about fish keeping is feeding so a auto feeder sort of cuts down your enjoyment
They can come in handy if you are going on holiday but as that's normally only once per year they are a bit of a waste of money as I think if I was going on holiday I would still want someone coming in to check on my tank as a auto feeder can't sort out a blocked filter stop a flood or remove a dead fish
