Service - naturally it may not be as easy to get Jebao on the phone, that being said, after the Aperture acquisition I am not sure that Ecotech support is so stellar anymore either, but definitely would expect ecotech to be superior there.
Longevity - we all have gotten used to placing vortech wet-sides somewhat regularly, and keep in mind that many have had to do bearing replacements on the dry sides, so though Vortechs are great, they were not immortal either.
I know there is some controversy here about the Ecotech Patent dated 2006, and I am no patent lawyer, but the idea for wetside/dryside magnetically coupled powerheads was patented in '69 and ecotech ran with that idea to make their 2006 patent which I think is good for 20 years (assuming their modifications to it do not reset that 20 year clock). It is discussed
here on R2R with patent references back in 2019.
Thanks for making this thread discussing your experiences!
