Has anyone used Boyu pumps?

Has anyone used BOYU Submersible Pump FP-28 for water circulation?
How good are they?

 

I'm currently using 1 in my 6ft, the pump is only a couple months old. So far so good. Price is also not bad at all

 

Hows the flow rate in your tank? The price is R129@ builders.

 

Its good I guess, but my water level is just about 43-45cm.
Tank is 1800l * 450w * 600h
I bought mine at builders aswell, good price hey.
and the petshops sell you cheap noisy crap pumps for much more than they worth.
the boyu is silent, even if I have to turn the power off for a while it still comes on silent. My pump in my 500lt display is just over a year old and has been a bit noisy since it was about 4 months old, if you switch it off for a while it comes on a little noisy and takes a while to run silent. the boyu does not do this.

 

I will get one soon. I'm going to use it in my malawi tank. I see its also minimal weight so it won't fall.
