Danner Mag 3
 

What is wrong with it?

They used to be common a few years ago but people stopped using them.

From what I have gathered they have good head and good flow but:

1. Have a relatively high heat dump.
2. Tend to leak around the O-ring.
3. Are not the quietest pump out there.
4. Are not the most reliable or longest lasting pumps.

Anyone have any other reasoning?

Anyone have any horror stories to tell about them?

I bought two for a good price and am wondering if I am going to regret it.
