It is a filter that does its job satisfactorily, it consistently and strongly produces oxygen, cleans the aquarium to a certain extent, mainly filtering the water and small impurities, it does not seem to have the power to be able to pull slightly larger ones

Quite good in its operation and easy to clean, but its performance drops quickly after two months.

Cleans the water just fine. However, be careful when a new machine is installed to monitor the nitrates and the water in general until a few days pass. One of our fish died, but now everything is fine

For me, it is a well-known product for its reliability, which is why I chose it again. Very good for small aquariums.

For the filter up to 60 liters, terrible perfect especially if you have soil underneath with plants it does nothing without extra materials which as a consequence will clog the water flow..stay away.

very strong! keeps the water clean

Disappointment in the effectiveness of the filtration. With no filter have I ever had cloudy water. It is a very simple filter with just a sponge. It does not support stages. Expensive for what it is. On the other hand, it is silent, except of course for the flow of water, it has good construction but what good is German sturdiness when a Chinese one at 1/3 the price gives incomparably better results....

I had it in an aquarium for 4 years, then I stopped having an aquarium for 10 years and I left it abandoned inside the empty aquarium. After 10 years, I decided to set up an aquarium again and used what I had from the old one. I didn't expect it to work, but I plugged it in and it works fine. So I am quite satisfied. As for noise, I find it quiet. The noise only comes from the water splashing, which can be adjusted by submerging it slightly below the surface.

I bought it to replace one that I have had for a while and it makes a noise that personally bothers me and makes more noise than the old one. So, the noiseless claim doesn't apply for me.

Very good filter for a heavily planted aquarium of 30 liters. The nozzle rotates to direct the flow. It also has adjustable flow intensity. Small in size and very quiet. Very good build quality.

The product has a 3-year European warranty and it does its job perfectly. For this price, I don't think it has any competitors.

I am not very satisfied. It was not easy to clean. It stopped working in less than a year. Affordable, relatively quiet.

Compared to the previous one I had, this one is top-notch. It cleans easily as the filter comes out smoothly from the top, leaving the base and suction cups stuck.

In a 120-liter aquarium, I clean it every 15 days.
The painting process with washing takes from 3 to 5 minutes.
