USB Single Sponge Filter, Small Aquarium Filter with Adjustable Hanging Clip and Suction Cup, Duckbill Outlet, Rain Pipe Outlet, Extra Spare Sponge

Works well. Would be nice to have a bit more water movement/output but it does the job. Nice small size with good filtration. VERY QUIET which is a huge plus. I’m not a fan of air pump sponge filters (even though they work well) due to the air pump noise. This one makes zero noise!

Update: it was user error. I realized after re-reading everything several times that I needed to squish the living daylights out of the sponge when I cleaned it. It's a beginner's error, as I thought I needed to be gentle with it. Once everything was clean, everything started flowing so nicely! However, still not full stars because the sponge does seem to be getting clogged/full rather quickly, after 2-3 days the water flow is starting to diminish already. Otherwise, it's great price point for a sponge that has its own pump included, plus the biomedia and flexibility to add to the container (I added a small amount of charcoal, for example, and previously seeded with old media). The flexibility and price point is really great for someone beginning the hobby! This was the original review: I'm so sad and frustrated. At just 4 days past the return period, I cannot get this filter to flow normally again. I cleaned the sponge at least 1x a week inside and outside, and scrubbed the intake. 2x within this month, I disassembled the pipes and scrubbed with a toothbrush and straw cleaning brush, and made sure to clean the little individual outlet holes of the "rain" attachment. Last night was the 2nd time I cleaned it this way, and for good measure I also opened the media recepticle and made sure it wasn't clogged with anything, plus scrubbed the intake from within that area. This filter has been steadily declining to now only outputting a dribble of water, and now I'm afraid my nitrogen cycle is crashing and my fish look stressed. There is no way to contact the seller after the 30 day period to try to troubleshoot, I cannot take the filter apart any further or I would void the warranty, so now I'm left to writing this review.

This sponge filter was great -- for five days. Then it stopped working and nothing that we did could get it going again.

Works well for small 10 gal betta tank. Would buy again

This filter work very well. The pump makes almost no noise, all you hear is the water flow. It's definitely worth the money. It's easy to setup and clean. My fish love it and so do I

I was sent the wrong size for my tank. I'm new to having fish as pets so I've been researching. This product is good however the output flow is way too strong and I didn't realize it until I started in the tank. I wish Amazon would pay attention to what they are doing. It didn't help that Hygger packaging and instruction are not thorough or make sense.

Way better than expected. Absolutely perfect for shrimp and breeding tanks

Worked well, but was way too large for my tank. It’s just way more powerful than you would need for a small tank. Was a little difficult ti figure out at first, but once you get it, it’s easy to use.

Items seems to work ok . Time will tell . Pieces missing but was able to rig up tube plug
