I give it 3 stars only for the volume. It is huge for what it offers. Essentially, you only have a sponge and if you wedge 8-10 macaroni exactly on top of the motor. Good build quality. Quiet without macaroni. With macaroni, they ring and may bother you. Nice and easy flow adjustment. It can go very low in flow for very small aquariums.

The truth is, it never caught my eye as a filter, but I decided to try it in a 20-liter tank. And the result is that I am amazed. I have tried dozens of hanging filters from all brands and I can say that by far it is the best in terms of noise! It's like it doesn't exist, it doesn't make the slightest sound.

It does the job, but really, those of you who say it's quiet probably have a different filter... It sounds like a stalled truck at idle. The lid is responsible for half of the dB because it doesn't fit perfectly, it doesn't have any kind of silicone or something similar to reduce vibrations. It's also very, very ugly. It only contains a sponge in a cassette that is easily removable. Good energy efficiency. But really, what can you do with such noise?

Quiet, the most important thing, incredibly easy to install, and does its job perfectly. I highly recommend it with closed eyes!

For now, it's very good, but in a 70-liter aquarium, I don't know how it will be in 200, which is its limit, and in a large turtle tank, not in fish with a lot of dirt, so it's worth its money, quiet, reliable
