Review: Worth every penny! - I recently purchased two of these Koi shelters after having an unknown animal clean out my Koi pond. This was my third Koi massacre, and I was heart broken! I got all new fish and I wanted to find some products that would offer them some protection. I have been very happy with these shelters. They are well made and larger then I had anticipated. They are barely visible in my pond. I have 11 Koi and one of these would have probably been sufficient, but I am glad I purchased two. Depending on the situation it gives the Koi options of where to go to hide and it gives me some peace of mind. I am also going to place a net over my pond. I think these things together will help keep the fish safe, or at least make it a lot more difficult for a predator to wipe out an entire pond. My only regret with this purchase is that I didn't make it sooner!
