I know EXACTLY what you are talking about gsd78. I asked the guy on ebay a question and he gave me a somewhat clear response. There is also the website, www.superfishstore.com
that used to say Jebo replaced their JebAO filter...but I feel I've got the thing figured out.
He calls his Jebo 828s and 825s..."The ones that replaced the JebAO 918 and 915". What he means is by his point of view, he stopped ordering the JebAO filters and started working with the Jebo company. The folks from Singapore also tell me they are different companies - they have had experience with these filters for some time. On http://www.arofanatics.com
I've seen treads titled "Jebo vs. Jebao", so they must be different.
I was told that both were once where the same company that split up. So it seems to me when they were both one company, they worked with US dealers. Now that they have split, JebAO remains in Asia and Europe, and Jebo works with the US/Canada. A theory I've heard is they are really the same company, but legally under different names. The Eheim has a patent in the US and the JebAO filters (Eheim-look alikes) got the boot. So now they have Jebo that's made up to compensate. And yeah, they don't look like Eheims anymore, just Fluvals.
Anyway, so I guess you have the JebAO 918, which is not really like the Jebo 828. How do you like it? Given you any problems? A JebAO dealer from Singapore said he could send me one if I wanted (in a bulk of at least 10, lol)...since they're not in the US anymore.
