The self watering design of these planters is very good, however, they should pre-drill a fill hole near the top on the back side of the planter where they have already pre-drilled the overflow hole near the bottom.  I don't think many people have a 3/4 inch drill bit.
Also, the material from which these planters are made is rather porous. Consequently, when filling the planter with potting soil, the rim gets stained from the soil.  So far, I haven't been able to clean it completely.
