Let me start by saying this little device has been a game-changer for my betta tank. The DaToo Automatic Fish Feeder kept my finned friend happily fed during a 10-day vacation, and I came home to a thriving fish instead of a disaster.

The setup was surprisingly easy. I used the adjustable clamp to attach it to my rimmed aquarium, and the whole process took less than 5 minutes. The moisture-proof design with the air hole is genius - no more clumpy, spoiled food even in my humid bathroom where the tank sits.

I love the flexibility of feeding options. For daily use, I set it to Mode 2 (twice daily feedings) at about position 3 on the portion dial. It dispenses just enough for my betta without overfeeding. Though fair warning - like some reviewers mentioned, portion consistency isn't perfect. Sometimes it drops 4-5 pellets when you might expect 3.

The battery life has been impressive so far (going on 2 months with original batteries), but I did take the advice of other users and replaced them before my vacation just in case. The lack of low battery indicator is definitely a con.

My only real complaint? Positioning is crucial. The first time I set it up, some food missed the tank entirely because I didn't angle it perfectly. After some trial and error though, I found the sweet spot where every pellet lands in the water.

For under $20, this feeder has given me peace of mind that my fish won't go hungry when life gets busy or when I travel. It's not flawless, but it's reliable enough that I've stopped worrying about finding fish sitters!
