Very elegant but unfortunately also very unstable.

I bought the planters here at Amazon.com in flash range of 100 and unfortunately have to say that I am very disappointed with the quality.
Visually the planters look very appealing and high quality, but a look into the interior gives an idea that has unfortunately eingesparrt very heavily in the stability. If you filled the loading bucket full of earth, the complete inner frame, which consists only of very thin metal rods, so that the whole planter breakup threatens to distort. Similarly Siehr out in the middle vessel. Only the boy is stable and is not threatening to break apart.
As a solution, I had only one solution to the problem. The loading bucket should be filled to 2/3 with Styrofoam so that still gives a planting depth of 13cm. And even then, the large vessel is anything but stable.

In conclusion, we can only say that these tubs are not in the least worth your money. The 100 are there just bearable but 150 is definitely way too much money for these planters.
