its a replica of an AquaC, so basically it is a spray injector skimmer...
IMHO, AquaC is still the better of the two, due to the following facts...
1) the weipro doesn't have the spray nozzle technology
2) AquaC has a bigger reaction box
3) the weipro skimmer cannot control the air intake
4) the weipro skimmer is made of cheaper material, plastic
5) weipro's buffer plate design is not correct
but then again, with this kinda price and the performance that it has shown in Chinmo's tank, its a good skimmer...
those are just my opinion, not here to shoot anyone...
