Most of the filters we use in the hobby are actully manufactured in China. Eheim...Fluval..Rena ECT. One exception to that rule is Marineland. The factorys who produce the canister in China very often rip off the basic design and then change it just enough to get by and produce it under thier own lable. The one your looking at is a rip off version of the Fluval 405 however it lacks MOST of the good features of the 405. parts availability and factory support on these units are almost non-existant. Personally I wouldn't risk it. None of these designs are properly tested or developed in any way. They rely on the originals for all of that.
