These pots will last you through MANY growing seasons. In the description, it states, "While plastic is not sustainable, we continue to offer them due to customer demand." One has to consider the word "sustainable". These pots will last me the rest of my life (granted, I'm an old geezer) and will then be passed on to my daughter, who is a subsistence grower. For me, that's a big plus - one of many considerations is that new pots won't have to be manufactured each year and I won't be wasting gasoline to go purchase them.
These pots are a little bit larger than I actually need for the individual cabbage and pepper plants I will put in them, but not so large as to take up too much space or be impossible to move. That extra size will also give me a bit of leeway on watering, etc.
I'm quite satisfied with this purchase.
