Review: Good upgrade - Better quality than expected. Works really well as a filter, which means I can clean the filter every 4 days or so. It's really easy to clean. I just take a jug of tank water and wash the sponge and filter bag in that. I've only had to clean the inner plastic twice with a brush, as it doesn't interfer with the working power. This was definitely an upgrade to the filter that we initially had. Also, he loves the water fall on it! I think it's a relatively quite filter, it's not much louder than the starter one, especially at night when the waterfall bit is under water level. It doesn't disrupt sleeping in the same room. Good quality for the price! If I had to pick it apart, some times it takes a couple of times to click it back together. But I'm very fragile anyways haha
Review: Excellent - Really impressed with this item, it works as it should, seem excellent quality with the advantage of extra connections. Highly recommend. Super easy to set up and use as well, much better flow than my last filter and fantastic value for mney with super speedy arrival.

### ⭐⭐⭐⭐ Very good filter - small, powerful and easy to set up/install
*by A***G on 29 April 2025*

This filter is very good, it's small but powerful. The size of it fits perfect in my 16L tank, it's quiet and doesn't make much noise at all which I like as it doesn't disturb me too much. The most noise it makes is a really quiet humming background noise but barely noticeable. The only negative thing is that it is very powerful so it moves my sand substrate around a lot, to avoid this I have placed my filter horizontally in my tank and now it is completely fine. The filter itself has suction cups and they are very strong when stuck to the glass, doesn't move at all. It's very easy to set up and install. Another good thing is that this filter comes with a filter sponge so I didn't need to buy that separately.
