Ahh the age old jebao question. You get what you pay for. I've run jebao returns pumps and powerheads. The biggest problem I have had with mine is calcium buildup causing them to stop. I have to soak them in vinegar and clean them up on occasion and then they work fine. I have heard power supplies are an issue also but have not experienced it as of yet. In my opinion they are a decent pump for the money. Don't buy them and expect the same results as a vortech or likewise though. I did replace my return pump with a waveline because of the problem of calcium buildup stopping my return pump. That was a problem for me. The power heads are not as big of a deal if they stop for a while.
