I would like to give it five stars but I had some issues with it.
First, it was delivered with a huge magnet instead of the attachment plastic shown in picture. When installing, the magnet is really, really hard to work with because of it's strength. But well in place the strength of the magnet holds everything in place.

The circulatory pump is really strong, for it's small size and it has a shrimp-safe water inlet. The inlet is easily blocked by small debris, leaves or bubbles and then the pump stands still and overheats. So it is not really reliable.

When I was putting the pieces together I noticed the tubing as hard to keep in place. And when I started the machine I noticed the tubing was constantly falling off the pump because of the centrifugal force of the water flow. I had to glue it into place.

But other than that I would really recommend it. It dissolves bubbles magnificently. I have to use just half the ammount of bubbles than with a ceramic diffuser.

I had some troubles in the beginning with the tube keep falling off but after a couple of days it started to stay in place. The pump was also noicy but the Very kind ppl on aquaristic fixed a sparepart in lightning speed so now it works perfectly. I've put it under the filter outflow so there is not much stuff getting into the diffuser pump.
Very efficient dissolving the CO2 and even if it is another thing in the aquarium it is at least looking cool with the bubbles swirling around.
Efficient gizmo for a reasonable price
