A great window box!


I've ordered a number of these boxes over the last 15 years or so. They do a great job with the self watering aspect of the box, only negative is that the water measuring things do take a beating after a year or so.

Great windowbox

Best flowerbox


I used these in a smaller size in direct sun and my flowers were always gorgeous. They never wilted. I just pulled them out today November 5th. Easy to fill up and easy to see if plants need watering . Best thing i ever bought for my deck!

Perfect solution for hard to reach areas.


The self watering feature is perfect for reducing maintenance and displaying our trailing flowers on top of our brick wall. They are perfect for these hard to reach areas. Well constructed and they are worry free.

I would buy this again.


The water level gauge on this window box is a great feature.

These windowboxes saved my flowers!


Put 4 of these on my second floor deck railing and the flowers have been beautiful all year. I am gone for 3-4 days at a time and the flowers would dry up without these pretty, self-watering boxes. Have had them for 3 years now. Just take them off the brackets and wrap them together in a tarp on the deck over winter. Just last week one of them fell during a storm (no idea how - the brackets were still in place) - so will replace it. Even falling two stories, it wasn't smashed, just one corner broken. Very durable.

I have purchased 3 of these


I am disappointed in the self watering part of these containers. My first one stopped working so we use that as a planter. The secon one stopped measuring so your company replaced it and it works. However, as you can see by the picture, it is almost impossible to fill the water container because the flowers are in the way. Maybe the water fill should be attached to the outside of the planter. It is just the right size for my deck and I recently ordered another one as I plan to use two of these on my front deck next year. (Even tho the water fill is inconvenient and doesn't always work)

disappointed returned it


The instructions are awful. The assembly bracket system complicated. Mounting requires additional wood framing for the boxes to be mounted against lap siding. Not worth the effort. I had to pay the cost of shipping return $15. Customer Service was helpful and courteous.
