I bought one this year as well. I have an above ground pool so I was able to plumb it in so you don't have to mess around with hooking it up to your return. I just have to turn one valve on and close the return valve part way and it's up and running.
I'm so glad you guys posted these pics! I saw one of these in one of the pool supply catalog and thought it seemed like a good idea, but wondered how it worked (and if the light would be too faint). Your pics tell me that I might have to look into getting on of these!
