The rack is very poorly constructed. The good news is that mistakes can be fixed with simple wooden spacers. The bad news is that you have to make a real effort to use it. But I knew it was happening from all the bad reviews. I figured I could just add my own braces and instead of making my own rack from scratch it would save me a lot of time and materials. And so it turned out. The stand is easy to assemble. The first solution I would suggest is to use super glue to glue the parts together in the slip joints. If you lift the top green part of the rack at all, the 3-piece tubes will come apart fairly easily. Glue helps, but does not eliminate fragility. The biggest problem with this rack is the lack of triangulation between the top and bottom horizontal parts. Throw in some heavy tools like regular old shovels and rakes and it twists, bends and sags like rubber. I added a 3/4" x 1.5" diagonal piece of wood on the back. First drill some pilot holes, then drill two drywall screws in the corners through the pipe joints. Then two more of the same diagonal wooden braces on the sides. This allows it to stand separate from the wall with tools inside without wobbling or sagging. When delivered, the rack has holes in the rear panels, which appear to be intended for mounting on a wall. Wall mounting does solve the sagging problem, but this shelf has wheels and is designed to be moved. And being wall mounted means the back row of tools is very tight against the wall and difficult to place or remove. The third problem is that there are only holes for 10 long-handled tools. The center slots are very narrow and none of the gardening tools I have fit in those gaps. I took a circular saw, cut those center slots into true round holes, and put five more tools inside. Next, the vertical black plastic tubes themselves would be great holes for storing tool handles, but the holes in the green top are too small. I also removed them to accommodate some 1" diameter tools. As a result, you can fit 10 tools on the shelf; At least 19 will fit with these mods and have the structural rigidity not to actually tip over. I wouldn't rotate it anyway, this feature is pretty much useless to me it seems clear that the makers and designers of this shelf must never have actually used it or tested it very thoroughly with real tools that people actually have in their garden sheds and garages.
