Thank you for the review, I was on the edge about these too. Might just have to go for it, seems like what I need, and less than half the cost of a MP40 is nice. Seems like i won't be trying to DIY a DC pump, these should work. Lifetime warranty, can't go wrong, right? According to this they seem to put out about the same water volume and flow pattern as a tunze 6105:

They are slightly more directional, and have a lot more velocity in the centre than the MP40's. But seem to be nice. And apparently they're quiet, which is one thing the MP40's can have issues with.

I am just trying out the different modes, and doing the Turbulence mode now, where I have each pump set at a different timing to get more random flow action. Definitely stirs things up in my tank, and my fish and corals will have to get used to the new flow patterns. I like the Feed mode (just touch a button), where it slow them down to minimum flow, and they go back to their current program automatically after a time period. Keeps my floating dry food from ending up in the overflow.
But what is really interesting is that these Coralife pumps fit the old Hydor Koralia magnet attachments exactly and I don't have to use the suction cups. So that concern is now gone. I can use the suction pumps for the lower flow Koralias. However, I am looking to see if I can get a hold of a couple more Koralia magnets, so if anyone has one they want to part out, please let me know.
I am sure these don't compare to the Vortechs, but the price is certainly a lot better. And so far, am very pleased with how they work. Lots of flow mode options, speeds, and timings, so will be trying them out.
