A very bad purchase!  Food does not stay dry & will clog up very quickly.  Flakes wouldn't drop after about 2 days. Pellets lasted a few days more.  I had one of these many years ago & it wasn't too bad, but still clogged after about 10 days.  Had hoped that this would be better than the old one. WRONG!!!
So, if you want a reason to get rid of your fish tank, use this and when you get back from vacation the fish will be dead or eaten by the bigger ones.  Then you can throw up your hands & sell the tank.

Seriously, this is a bad product.
