Negative Positive
Title: Glad I tested it before leaving!
Review: Before I bought these feeders I noticed the reviews were all over the place. Some people loved them while others came home to find their fish had died. So I bought them and decided to try one out before I left for vacation. I'm very glad I did because nothing happened. While it seemed to be dissolving I couldn't see any type of food being distributed. My Beta did not have a clue as to how to eat from it because he normally chases food from the top. He doesn't forage on the bottom of the tank. After 3 days I decided to take it out of the tank and use a mechanical feeder. I think if I had just dropped it in the tank and gone on vacation I too may have come home to a dead fish. They seem worthless to me.
