If you have the budget, then would advice you to go for Eheim!
It's sure to last you longer than any chinese made ones in the market!
Replacement parts are easily available too!
And one important factor would be the constant flowrate.
Unlike their chinese counterparts where flowrate would reduced over time
However, quality do come with a price!
Ehiem filters easily cost 2 to 3 time then their chinese counterparts!
I believe many bros here have their Ehiem filter last long as their hobby (> 6yrs)!
As for the chinese-made ones, i would say its value for money!
Quality-wise, i consider them reasonable, consider the amount paid!
If you are looking for chinese-made one, I personally would recommend Atman!
I have 4 cannisters from them running as of now!
But only can afford an Ehiem!
And many chinese-made ones have smaller models for smaller tanks!
You can adjust the flowrate with the tap included!
Sorrie for the long comment!
Hope it helps!
