Frst, I love tht it's made in the USA (Ohio). There is no 'assembly', they are a molded product.  The self-watering feature is great when I'm away for a few days during summer - don't have to nag anyone else to water.  They look geat - the whte is an optic white. While they are very lightweight empy, with the water reservoir filled and dirt added, they won't be affected by wind.
