These filters have come up in numerous threads. It seems like no one really knows how good they are, and I believe only one or two members from this site have them. (at least to my knowledge) I believe they run well and work well for a while, then start to leak. If you end up getting one let me know, or post in this thread so we can finally figure out how good or bad these filters really are.
its a knockoff.. so like with any knockoff some will say they are great and some will say they are crap...
IMO if it works half as well as it says it does and costs 1/4 of the original then its great...
as for leaks... all canisters leak.. my brand new eheim leaked right out of the box.. my used jebo didnt leak untill the third time i opened it... a touch of silicone fixes everything...
