Great quality. Nice insert shelf for the inside so we sat the pot with the grass right on top. I bought a two pack. 

They are a good weight on there own but to play it safe we bought a bag of rocks, placed the rocks in ziplock bags and placed multiple bags of rocks on the bottom of each planter to prevent them from tipping over if it were to get particularly windy.

These planters are on a NYC terrace and condo rules specify that only non-rusting planters are to be used on the terraces. 

Very satisfied and pleased with this purchase.!
