Review on Ycozy Rechargeable Automatic Fish Feeder with USB Cable - Moisture-Proof Electric Fish/Turtle Feeder for Aquarium & Fish Tank - Intelligent Timer Fish Food Dispenser for Vacation - Navi-EV by William Rothstein

This feeder works well. I found it easy to assemble and followed the instructions. We are tourists so in the warmer months we go to camp either for a week or just for the weekend. This feeder gives me peace of mind that my fish friends will still be fed when I'm gone. Feeding intervals are 12, 24 or 48 hours. I think this is a fairly common feeding time. We usually feed ours in the morning and later in the evening so I use the 12 hour setting to follow our regular schedule. You can choose the amount of feed. I usually stick to smaller portions since we feed twice a day. I think he's releasing a little more than usual, but that's ok. As long as we're happy.
