Query: I have only had this product for a few days, therefore I'm giving it 4 stars not 5, however so far I'm very happy with this corner shelf, I needed some shelf space in my shower and hate those springing corner shelf that just rust and cause mold to grow behind them, these shelves are high quality plastic and suck into the corners very well, they are a little pricy, but so far worth the cost.
