"For starters these things will break if you look at them wrong. The resin they're made from is absurdly delicate, and on top of that there are sharp protrusions that tend to form on the inside where the resin is sticking up (think stalagtites) Fragility and lacking Q.C. aside let's move on to inherent design flaws. The underside actually curves in providing a place where a snake can ball up and become nearly impossible to remove. All in all this product is a major failure as a snake habitat addidition. It might work if you have lizards, but even then the piece is far too fragile for practical cleaning even. I give this thing two thumbs down."
