I've been using the SLSON Aquarium Coral Feeder for about a month now in my planted betta tank, and it's been a mixed bag. The 20-inch length is perfect for reaching deep into my 5-gallon tank without getting my hands wet, which is a huge plus.

The suction works decently for cleaning up debris and uneaten food around my betta and snails. I particularly like how it doesn't disturb my plants while cleaning. The measurement markings are super helpful for precise feeding - no more guessing with liquid fertilizers!

However, the extension pieces don't stay connected well during use. I've had water leak from the joints multiple times mid-cleaning. The rubber connector feels flimsy, and the whole assembly wobbles when extended fully. Also wish the bulb held more volume - I find myself refilling too often when spot-cleaning.

For basic maintenance in smaller tanks, it gets the job done if you don't mind some quirks. But if you have a deep tank or need strong, consistent suction, you might want to look at other options.
