Wonderful quality.  I really like that, since they're not wood, they won't rot.  The black color matches my patio table and chairs.  Also, black won't show mold and mildew which we have a lot of in Oregon.  I'm not sure how the self watering and small drain hole will work out when I plant them in the spring.  It appears that I can probably drill additional drain holes, if needed.  I would like to review this product a year from now when I have had more experience with the product.
