Review on Gallon Aquarium Divider Suction Cups by Katie Garcia

I have to say it fits my 20 gallon tank perfectly, nice and snug. Maybe a little too stealthy, but at a slight angle it works. I kept it under a huge stack of heavy books for days and it didn't do anything to smooth it out. It comes rolled in a thin box and mostly rolled almost permanently. If you straighten it by overlapping the edges, you'll get some warping. Mine also had a few cracked holes as shown in the second picture, as if trying to smooth out the semi-flexible rubber-plastic material broke it. The screws are plastic, they break SUPER easily. But they give you a lot. Overall I'd say I'd buy this for maybe $9.99 but definitely not $20!
