      I just ordered my second set of self-watering boxes. The first ones graced our deck for close to a decade and still looked good despite the inevitable signs of aging .
      I expect this set to perform just as well . I am sorry that there aren't more color choices .. Like a blue or green ..

      Comments about 39" Self-Watering Windowbox:

      This self watering window box does the job. I rarely have to add water to the reservoir, or even water the plants in the box. My plants thrived in these boxes and I plan to get more to replace all my coco lined planters. I just wish it came in a more attractive finish. Bronze is not a good description of the color, it's more of a dark dirt brown. A green finish would be nice. The mounting hardware and mounting directions are not particularly good. The brackets that are supposed to support the bottom are useless because they are way too short to mount the box on a deck railing. When the box is full of dirt it is heavy. When water is added is is very heavy and it really needs the bottom mounting brackets for support.

            This is my second box and I really like these. I have not used the hanging feature, I just set them on a railing or table. Wish they came in green. This is a TRUE self-watering planter and the little gauge and watering setup works very well. Didn't go 5 stars only because I haven't tried the hanging gear.

              We have six total hanging over the railings of our deck where they provide extra plant space without taking up floor space. The hubby questioned the price, but I love the quality, and I know they'll last. The supports are easy to assemble and hold full loaded boxes. Love these!

                After buying two window boxes, attaching them to my house and planting them, I then ordered four more. After I had put all the soil I purchased from Gardener's in the new boxes, I had a party of four friends and served cocktails outside in my garden where everyone's chair faced the house and the window boxes. Then MANY colius and all sorts of shady plants were put in front of each person and they had their own box to plant. We had so much fun and everything was planted and I didn't have to do a thing!!!!!. Hurrah!!!

                  I had 6 of these that I bought 8 years ago. They lasted well enough but 2 of them seemed to always leak from the bottom. I thought maybe I did something although I am very careful. And the water guages on 2 of them were iffy. I replaced 4 this year and same problem with one of them! already planted so I can't return. Plastic must be split at seam on bottom. frustrated.
                  BE SURE to fill with water BEFORE you plant to see if there are any leaks.

                      This is the second time I have bought these planters. I have two planters on the outside of my deck handrail... easy to mount does not take up deck space!. The last ones lasted for many years, but really needed to be replaced. I love this color (bronze). The self watering feature is great, but you need to clean them out / store properly when not in use to avoid issues.
