Great quality!  Can I say perfect! Big and deep! This will hold most of my herbs this summer. Fairly easy to put together. Had to recruit muscles to get the screws to go in the plastic holes; but I did get it done. Remember to have this is the exact spot you want before filling with water and soil. It is heavy.  Very sturdy. I am sure I will get many years of use.  The depth is probably what I am most excited about. I was so impressed, I ordered another.
