Review on 📦 MACRO GLOBE 5-Tier Changeable Assembly Carbon Steel Standing Shelf Units – Heavy Duty Shelving Unit with 350 lbs Loading Capacity – Wire Shelving Unit for Home and Kitchen – Size: 21.25" x 11.42" x 59.06" (Black) by Sherrie Webb

Metal and plastic don't mix. Metal shelves and metal bars arrived in excellent condition. This thing comes with plastic clips that break off when you try to attach it to the bar (per the instructions). I even tried to connect the clamps together with a vise, but no: they jumped off the rack and flew the other way. The instructions state that you must "gently" tap the clips at the corners of each shelf: I've never passed one because the clips popped out in a different direction when I tried to assemble them. I had to return (that I was nailed with a restocking fee). I would not recommend this product (as is) nor would I buy it again (as is)
