I ordered Jecod CP-40 3 days ago from Fish Street and it arrived today.
The CP-40 is for my 120 (48" x 24" x 24"). It replaces two Tunze 6105's controlled by an Apex, and one Jebao WP-40. I was mostly happy with these 3 powerheads, except they are bulky and unsightly in the tank, and there is too much flow right in front of the powerheads which has damaged corals.
The CP-40 has been running now for an hour. I have it installed horizontally on the top right of the tank, a few inches down from the water surface. It is currently set on steady mode (no wave or oscillation) and maximum intensity. It gives a good gyre flow all the way to the other end of the tank. There looks to be a dead spot between the two overflows as expected.
This pump does not make any noise at all. I can see it vibrating slightly up and down at a frequency of about 15 hertz so this tells me something could wear out sooner or later. It is definitely an aesthetic improvement over the 3 powerheads.
One worry is that as the sole pump in the tank, if it stops when I am away for a few days, all my corals die. With 3 powerheads one can go and everything will be fine. I will probably mount an extra powerhead for this reason, at least when I am out of town.
Here are a couple of vids before and after swapping out the powerheads:
