When I started having problems with my Eheim 2217 a while back I started looking at a cheap replacement for it and The Jebo seemed to be the best bang for the buck I did find a review from a guy by searching for a review on the one I was buying and got a post on a forum from 3 years ago showing detailed pics of the filter what came with it and him setting it up and doing flow tests on it with and without media in it. then on the last page of the thread was an update 2 years later saying he was still happy with the filter everything was still working like the day he bought it.
Not sure if it will last as long as my 2217 had it says it was made in West Germany not Germany like newer ones I've seen.
