hydor wave maker

I've posted a few times about this but I'm not getting any responses. I am setting up a 40B DT with 20T sump for a SPS dominant reef tank. I am going to be placing an order for remaining equipment that I need but I'm looking for feedback and opinions on the following: - Hydor Koralia Powerheads...

I bought and use that for about 1 month and upgrade my pump to Vortech so no use of it now, selling for 45$ with shipping, do come with original box.
