I've been using the Aysoner Automatic Fish Feeder for about a month now, and it's completely changed how I care for my betta when I'm away. The first thing that impressed me was how compact it is - it fits perfectly on my 5-gallon tank without being obtrusive.
The rechargeable feature is a game-changer. I love that I don't have to worry about buying batteries, and it continues working while charging. During testing, I found it dispenses about 1 teaspoon max (perfect for my single betta), though it did take a few trial runs to get the portion size just right.
One night when working late, I actually forgot to feed Mr. Bubbles - but the feeder had my back! Waking up to see him happily swimming around his normally scheduled breakfast was such a relief. The 360° rotation ensures food spreads evenly, though I did notice occasional portion inconsistencies that others mentioned.
The included feeding ring is genius - it keeps the food from scattering everywhere. While the container is smaller than some feeders (holds about 2 weeks of food for my setup), this actually works better for me as it forces me to refresh the food more often.
Would I recommend it? Absolutely - especially for small tanks and busy fish parents. Just be prepared to test portions thoroughly before your first trip away!
