      We are so happy with this window box. It is on our outdoor shed at some distance from water source so having this self-watering is not only handy but really works. The lobelia are doing better than any other year.

      I love it for the looks, exactly what I need under a small garage window. Husband hates it for the difficulties he had attaching it to the window and siding without causing damage to either.

        I've had these for over twenty years and they are still in wonderful shape. I did need a new water level last year, and GS has them in stock. Gorgeous, durable, and effective.

          These planters have been under my front windows for 20 years. They are in full Southern sun, and the water reservoirs keep them healthy all summer. Recently I bought another one for a back window, and the new ones are of the same quality. Very attractive.

                The instructions say to drill the bottom with a 1/8th in bit. It should be much larger because drainage is a problem. Small plants drown. I would highly recommend you fill it with larger flowering plants. Not good for starters. And drill a much larger hole in the bottom.

                  As I said earlier, it is in a spot that gets midday sun, but it holds moisture well. The watering system prevents creating messes on the porch wall behind the box. Also, can be filled with a pitcher and I do not have to drag the hose up on the front porch to fill it.
