After testing this feeder for a month with my tropical community tank, I'm officially spoiled. The 2.4GHz WiFi connectivity (when it works) lets me feed my neon tetras from bed or even during work trips. The push-pull mechanism genuinely prevents clumping - a huge upgrade from my old feeder that turned flakes into mush.

The four interchangeable food bins handle my 1.5mm micro pellets perfectly, though like other reviewers noted, flakes are a no-go. Pro tip: The optional 450ML extension tank is worth buying if you travel often - I loaded mine with a month's supply of pellets before my Costa Rica trip.

Where this shines: The feeding consistency transformed my fish's health. My usually shy dwarf gourami now swims to the surface like clockwork at 9AM and 5PM feedings. The app's history log (when accessible) provides peace of mind - I could see it dispensed food during a 3-day power outage when I was away.

Major caveat: The app dependency is this product's Achilles' heel. Like some reviewers experienced, I temporarily lost access during an app update. While mine reconnected after resetting, the password reset glitch others described sounds infuriating. Always keep the manual feeding button as backup.

Installation took under 5 minutes using the adjustable clamp on my rimless tank. Unlike traditional feeders, the four fulcrum points let it perch securely on my nano tank's feeding opening without blocking the lid completely (though cat owners should still improvise coverage).

Final verdict: At its best, this is aquarium automation done right - but have a contingency plan for potential app issues. When functional, it's worth every penny for consistent feedings and travel freedom.
