I have first the identical model, only smaller (200L) bought, but it was too small. So I gave the vase a neighbor u. I bought the next larger model (360l). I would prefer the even more with 500l been, but that would not have coped with my little terrace. Form, function u. Top quality. However, I have up inside it, cut a round hole, so that the - the highest possible -. Following the downspout was easier and also an interior cleaning. The hole I have covered with a household spray protection for the pan (33cm Durchschniit). On a plantation as on the product presentation I have to forego so, but I never had before. PS: the drain hose is connected to a located just above the bottom opening, which is not seen on the product image, as it is behind. For example, the vase can completely empty.
