I've got 4 jebao wave makers (2x RW's and 2x PP's). The RW's both died around 3.5 years old, but to be fair they are so encrusted in coralline so I wouldn't be surprised if they will start working again after a good clean (I've been meaning to get around to it). Or maybe they would have lasted longer if I had of taken care of them.
The PP's are almost 2 years old and going strong.
At the end of last year I got 2x Coral Box QP-16 wave makers and so far they are going great, can't speak to their longevity yet though.
I've also got a Jebao DCT6000 and have had it running as my return for almost 4 years now and it's going fine (although I would recommend going 1-2 sizes up than what you want with the Jebao return pumps).
I also had a Jebao DP-4 doser which lasted almost 2 years before it died (and it was second hand already). And really the pump itself didn't die, the tubes inside the motors just needed replacing (which happens on all dosers over time) but I used it as an excuse to pick up the new coral box doser anyway which is awesome
I think you can get burned when you buy cheap gear, it's cheap for a reason, usually because the company didn't need to do much (if any) R&D and they cut corners on components, quality control and customer service. But at the same time I think its no where near as often an occurrence as people make it seem.
Think about how many jebao pumps there are out there compared to vortechs. Absolutely heaps, I would bet that there are way more jebao pumps than any other brand, so of course you are bound to hear more bad things about them just due to the sheer volume that are out there. And they are cheap, so the occasional bad one does slip through quality control.
Given my good experience with the brand I do recommend Jebao to people. But I also strongly recommend that they take advantage of the extremely cheap prices and order a spare of each essential item, who cares if it sits on the shelf for 4 years, you can sleep soundly knowing it's there if you ever need it!
Lets say you want 4x wave makers and 1x return for your tank. You can get 5-6x Jebao wave makers (1-2 spares) and 2x Jebao returns (1 spare) for pretty much the same price as only 2 vortechs. Even if you have 1 or 2 failures every 2-3 years and need to replace them it would likely take years before you come up to the same cost as the 'good' gear (unless you are crazy unlucky with a seriously high number of failures).
And in that time Jebao may have even released some new cheap pumps you want to try out anyway
