Pieces fit together perfectly. Strength seems better than other brands too.

It did the job for us, very sturdy and size is good for our fall's base.

Created a pump/barley straw pellet housing for my pond with this, who ever designed this it made my day easier

I bought these to use on my Koi pond. We needed to cover it to prevent the kids from falling into it. We stacked them up and then covered the top with flagstone to make our pond into a pond less water feature… we left the bubbler and sump pump in place. Now we gave a water feature without the dangers of a pond for small kids or pets. The plastic material and pattern on the cages makes it pretty strong, we can walk on top with ease. These gave worked out perfectly for us.

I’m using it to keep water lilies at the right depth in my fountain/koi pond, and it’s perfect for that. It’s transformed my pond—my koi spawned! (Check it out—I’m a poet and I didn’t know it.) I guess all they needed was a little privacy.
