For the comments on Eheim not being comparable because of price, and them being outrageous-
I've got an Eheim 2217 and I absolutely love it. I can't imagine a canister (of a similar size) that I would like more.
I'm looking to buy a couple Jebos right now. I can get a deal if I two of them for the same price I can get one 2217 (almost exactly the same price, actually!), and at that, each one should be about comparable to my Eheim for filtration ability, and if they actually perform up to what they're rated, they'd be better. So, yes, Eheims are outrageous compared to the cheapest canister on the market, which is a knockoff of the Eheim design.
Now, compare Eheims to other brands & models-
At Drs. Foster & Smith you can get a 2213 for $76, up to a 2217 for $125. A Fluval 405 (which should be comparable to the 2217) is $200+shipping at Foster & Smith, or $234 shipped on eBay. That makes Eheim, which is generally regarded as one of the best filters out there, if not the best, actually a good bit cheaper. When I look at this, I don't understand how people can say an Eheim is such a bad deal. A 2217 is comparable to the 405, and cheaper. A LOT cheaper.
The 2217 is roughly comparable to the Rena XP3, which is regarded as inferior to the Eheim by almost everyone who has used both, and it's only $20 more than the XP3. The 2213 is $20 cheaper than a Magnum 350, and with the only 350 I've ever touched (on a tank I clean), the 2213 is about twice the filter a 350 is.
It seems to me that Eheims aren't so insanely expensive as everyone thinks. And now compare- a Jebo 829 is $105 shipped from ebay. Compare that to the $135+$15 shipping a 2217 costs from Foster & Smith, and that's a $45 difference. $45 isn't that much of a difference when you're talking about a brand that's been around forever and a model that some people have had running continuously for 15 years. No one knows how the Jebos will age, and Eheims are pretty durable.
Now, I'm looking for a secondary filter to add on to my tank, just because it can't hurt to be over-filtered. And with the Jebos, I can get my secondary filter for my 90 gallon, and a canister to use for my axolotls who will be going in a 60 gallon, and it'll be the same price as one more 2217. In my eyes, it's not exactly a tough call. . . But we're talking two entirely different things here.
And onto Jebos- I hear more & more good things about them every time I look. I've been looking into them a TON, and one thing I've found about all the negative reviews on Jebo is that at least 3 in every 5 negative reviews of a Jebo is actually a review of a Jebao, which is a knockoff of Jebo. And probably half of the complaints on the filter are that they were shipped in broken. That's not the fault of the company producing them- it's the fault of whoever you're buying it from. If you bought a refrigerator from Lowes and they dropped it off the truck when they delivered it, would you blame Lowes or say that Frigidaire makes an inferior quality product?
The most common negative I've found of Jebos is that they make a mess if you open them wrong, and they really only work on a tank about half the size they're rated for (which is about standard for most canisters).
