How does it perform? Well, it is extremely powerful, compact and built like a tank. Contrary to what the manufacturer would lead you to believe, it does not run hot (33 degrees C for the motor housing).

But it does have that limited 2500 hrs. MTBF, and it is a bit noisy --a bit like the Laing 4 from DangerDen, I'd wager.

As such I have decided to swap it for a Davies-Craig EBP pump; practically identical, but with a shorter body, half the flow, but 15000+ hrs. MTBF. It is also reasonably quiet. Cathar runs one so he should be able to tell you more.
