The dimensions are slightly smaller than advertised, but the capacity is accurate (20 liters exactly). It comes with a low-flow three-stage filter, which produces minimal noise (it is completely eliminated if one unplugs it and plugs it back in a few times). However, it is bulky, taking up quite a bit of usable space. Also, it seems that it does not clean perfectly. For almost a week, I noticed a slight cloudiness in the water (which disappeared immediately with the use of amtra filpo 300). The plastic parts are of good quality, except for the foldable feeder which, at least in the piece I received, comes out of its position easily. The lighting is acceptable (3 watt cold temperature white LED), but it may not be sufficient for plants. Overall, I would say that the K20 is a decent low-budget package. It doesn't have anything particularly impressive, but it also doesn't have anything particularly bad or dysfunctional.
Decent entry-level aquarium or for small spaces. Its filter is quite large, quiet but a little bulky (you can remove the sponge and add biomaterials). The lid is a bit loose (snap-on, no lock). I have had it for three months in a child's room with guppies without any problems.
