Hagen Nutramatic 2X Automatic Fish Feeder

  I have brought three of these fish feeders in the past year, they work initially but after a couple of days the food starts to clump and its very unpredicable how much feed is given out (sometimes none). After using the fish feed for a couple of times they seem to just stop working. I would really not recommend this fish feeder to people, i found that the sera one was much better, it didnt look the best but works really reliabley\n  richard
