Thought I would post my experiences with the WP25's as well. For the record, I'm slightly still in favor of them. Bought my first one in August from Fish Street. Liked it so much that I bought another a month later. Replaced three Koralia's with the 2 WP25's and the tank seemed to love the flow. I keep both in Else mode, and usually alternate and set one or the other on W1 S1 over the weekend for a little variety. Last Friday, set the left one (the one originally purchased in August) to wave mode before going to sleep. Woke up the next morning and noticed no wave action happening. Checked the pump, cycled power a few times, removed to clean, but still no go. Swapped controllers, and it was definitely the pump itself that died (it was pretty warm when I removed to clean). To their credit, Fish Street agreed to ship a replacement for $10 shipping, so it's now on the way.
I had hoped to get more than 3 months out of a pump, so time will tell how much of a bargain these really are. I was absolutely sold on these at first, considerably less sold on them now. We'll see in 6 months or so how much of a bargain they really are.
