Summary: They are definitely made for the workshop as the fit and finish are average to poor. Good for holding heavy tools like hammers. Observations: The first thing I noticed was sloppy weld spatter everywhere. There were several sharp spots, the edges of the incisions were not cleaned, most were sharp. One of the brackets has been optically rotated (3 degrees). The rear lugs were not flush with the horizontal faces. The green part is nothing more than a thin, thin ribbon. Recommendation: I've added a picture of my current tool holder, which is a stainless steel magnetic knife holder. This one will definitely hold more weight. Pros: Strong magnets; includes 2 mounting screws (I threw them away and replaced them with stainless steel parts). Cons: Average - Poor fit and finish (weld spatter, misalignment/sloppy fit). Bottom line: $13 for the 13" and $18 for the 24" which got 3 stars for lack of quality control.
