This is the 3rd feeder we purchased of the same type. When it works, it is great. However, after installing this one, within the first 2 days, the nozzle came off when dispensing food and all the food fell into the pond. It took me 2 hours to remove most of the excess food. We assumed it was a racoon that pulled it off in the night, so set up a barrier and reinstalled it. When advancing the food after the 2nd installation, the nozzle came off again. I was able to capture most of the food in a container I had, but still lost a large amount of food that had to be skimmed out of the pond again. I have now taped the nozzle on to the base and it seems to be working fine. This was an expensive loss of good koi food.
