I am VERY displeased with this shelf. Purchased for reptile tanks and its VERY flimsy.  Put the tanks on it and it easily wobbles and no way to mount it to the wall to help stabilize it. I have purchased several shelves and this one was the most expensive and so far the worst. Went to return but due to the size its gonna cost me half what i paid for it to return it so guess im stuck figuring something out to do with it or id be out of about $50. Very disappointed. Now im stuck with a shelf idk what to do with.
