I really like my Renas (XP3 and an XP1) but since this is a forum and the goal of these forums is to spread fact based/experience gleaned info, I must be honest.
I prefer the Eheim classic line thoroughly over ANY other filter. There, I said it. I know those of you whom have meandered over to the Eheim version of this thread (or even the SUNSUN thread where I feel compelled to try my hardest to stop people from buying cheap equipment when associated with this hobby as the consequences will likely prove themselves much, much more costly than what they saved initially!) have read my dissertation on canister filtration.
Don't get me wrong, the Renas are MUCH easier to service, prime and disassemble. But for me the lower consumption of power, more efficient cleansing of water, quieter operation, longer service intervals that the 0 bypass design promotes (you dont get clogged up channels of flow with the classics so the flow drop is much slower and more linear as compared to the XP series IME) and just the crazy dependability/reliability I have experienced throughout the years.
I HAVE A 2217 THAT HAS THE MARKING "MADE IN WEST GERMANY" ON THE PUMP/MOTOR HOUSING!!! Cant really get more clear than that.
I will never buy another filter other than a classic Eheim but I also will not let people try to misrepresent Rena XP's as they are damn fine pieces of equipment. IMO, just not the damnest or finest.
