No troll here. Just speaking from experience. Less noise, less money and equal performance.
Less noise, obviously. One pump is completely underwater (muffles quite a bit of sound) and doesn't transfer power from the outside of your tank to the small internal wetside which produces noise. Less money, once again no brainer. Jabao are made in China by Chinese laborers with cheaper, less reliable materials from designs they re-purposed (Tunze) not engineered from scratch.
Less money is probably where I would have ended that post as saying they have equal performance is just plain wrong, regardless of whether you use Jabao, Ecotech, a combination of both, or none, to think that a product that has been on the market for about 1.5 years which such a drastically lower cost/higher failure rate/completely different operating structure as a Vortech. I have yet to come across any market, reef tanks or otherwise where you can buy something for 8 times cheaper than another product and get a better product. Perhaps I am just a foolish consumer by thinking you generally get what you pay for. From what I understand, Jabao's produce narrow, strong flows from pumps that are ran with the motor inside the tank. Vortechs produce broad, strong flows that eliminate the need for aiming powerheads around. When it comes to cheap Chinese goods, especially ones that haven't been out nearly long enough to determine any type of longevity, I'd rather err on the side of caution with ending up with some stray voltage from the Jabao.
I could care less about a wire in the tank.
Looks horrendous to me, especially on small tanks where real estate is limited. I'd rather have as little of the pump inside the tank as possible and look at my fish and corals, not 4" long Chinese powerheads with black powercords hanging out of the tank.
