Koi Shelter - Okay

I purchased the solid plastic koi shelter. I like the product, except for the fact that it has absolutely no weight to it and there was no way to anchor it to the bottom of the pond. Throughout the summer I would notice it randomly floating around my pond, on it's side, etc. which was a bit frustrating. When it was in place it was great, but this was/is a big fault.


Little cheap and too light

For the money - nearly $50 for the solid 21 inch product, I thought the item would be much heavier and sink on its own and stay sunk. Very thin and flimsy. I just climbed out of the pond in 40 degree temps after trying to weight the things down without flattening them. I have some small to medium sized rocks leaning against the item so we'll see if it stays put. I bought 2 so not sure there is $100 of value here. Suspect I was better off not giving up looking for a Brown Clay Pipe that would stay sunk and not move.
