First of all, I'm really satisfied with my boxes! They seem robust and stable, are easy to fix and there is no disturbing visual holders. TIP: before the final "assembly" of the Fixing clips: clips lightly inserting and turn upside down boxes above the railing. The insertion should preferably be done by both sides at the same groove around the box to be mounted horizontally as possible. After precise adjustment: 1. is noted at which groove used exactly (saves at the other pots / boxes the sample plug) 2. empty box flipped place on the ground, so you can push in the Steckklips strong (!). ;-) Emergency gently knocking with a small hammer something Then you can replant and replace the box ready! When planting it is necessary to consider, however, that is in the box mid-high line: plants with large root balls are not easily put; (This is for me eig also pretty much the only shortcoming or tips for installation of Fixing clips might boxes might. still accompanied by: would make the first attempt at a relaxed and easier Optically a wonderfully successful thing ;-))!
