Hydor Koralia Magnum 8?

[GreenSpottedPuffer]

I was going to buy the MP40 Vortech but I am wondering if the new Koralia's might be worth looking into. Half the price too!

Anyone using any of the new Magnum powerheads?

I have had 4 of 8 koralia powerheads fail (either just stop working or leak voltage), another one break at the magnet holder and another the magnet was getting wet and rusted in my tank. So I have had problems with so many of them that I wasn't even going to consider buying Koralia again but maybe the magnums are better?
