I do it very briefly: it is not high quality, I was on the other reviews here clearly. However, if it works, I thought, it does not matter. Simple Styrofoam covered with reflective foil stuck, unfortunately is not even de anchors (plug bottom of the pyramid with around wound string) so stable that you can from time to time change the length. But that would be necessary for me, because the water level often varriert. In a larger pond may not care. After about 8 weeks now but unfortunately the mirror film "scuffed", otherwise I can not describe it. Ok, we had certainly heavy rains in May / June 2013 but I already expected that it is weatherproof and not after a few rains blind. Whether it worked in the 2 months? At least no fish are gone from us in time, should be although herons with us. I'm going to at least get me a higher quality version of it, the attempt is worth it. But the thing here is for the ton
