Absolutely amazing - I was able to use the styrofoam that this came with to pack the bottom of the planter, and I bought 11 herbs (lavender, catnip, parsley, cilantro, dill, chives, thai basil, sage, thyme, rosemary, oregano) that all fit perfectly in here. I'm thrilled with how sturdy it's been on my 19th floor balcony; unlike the other planters I bought, this has not toppled over once - and I'm sure it won't.
