One of the most positive characteristics of this product is its versatility. We were able to sit down and really walk through which of the 10 possible designs would be best for our space. In the end, we choose the 4'x8' option. I chose to go with the taller product and am glad I did. The extra height is going to be a back saver for many years. My only concern is that customers not familiar with vertical gardening like this, will be surprised by the volume of material needed to fill the interior. I wish the company could provide an example like, the unit requires approximately 70 bags of soil or something to that extent. The only con is the sheer volume of screws. I put the entire unit together by myself and while not hard, it was INCREDIBLY time consuming and can be awkward as more pieces get added. I would 100% recommend this product to anyone interested in gardening where space is restricted.
