I have had this for over a year. It has been a life saver when leaving on vacation or knowing I won't be home to feed the fish. It has many different programs. You can set it to feed multiple times a day and have it turn once per feeding time or twice. The opening is adjustable so you can have a lot come out or a little.
This had been reliable and I am extremely pleased with all the functions it offers! I would definitely recommend it!
