cheap chinese knocks offs are about as good as michael jackson doing jail time.
I am not sure this added much to this thread.
FYI, much of the stuff you see labeled as MFG was actually manufactured in China with specific designs handed to them to copy.
often you will find these 'cheap' Chinese knock off companies parts in the higher priced items.
the point to this is that there are inexpensive alternatives that seem to work well.
this filter is apparently a 'knock-off' of the Eheim..not near the same quality but none the less it works well and is an inexpensive alternative.
this allows new users who do not have a lot of money to purchase a filter that will work fairly well.
at around $60 shipped it is considerably less expensive .
