I've used dozens of Jebao products over the past 10 years and only had to replace one flow pump in all that time. For the price, I can buy 2 or 3 to keep as spares and still come out way ahead over the 'name brand' stuff. I can't speak for everything they make, but I've had great experiences with them.Whatever you save is only short term; you typically end up replacing Jebao equipment within a year or two, so you'd have been better off with a non-knockoff product with better construction, warranty and reliability (not to mention performance).
