Easy assembly though tedious and time consuming) A Phillips head screwdriver is needed, and I recommend a 10mm deep socket wrench or box wrench to more easily tighten the bolts. The parts fit exactly, no misalignment of the punched assembly holes. When assemnled the unit was fairly rigid, and can be carried by the center stiffeners to the garden. I put it together in the driveway, which is reasonably flat. My unit has a gray enameled finish, and blends in easily with the foundation of my house. The finish is protected from scratches in transit by a thin plastic film (which is annoying to peel off), also, the top and bottom edges are rolled, so no sharp edges after assembly. I hope the enameled finish lasts! I only wish the corrugated steel was thicker, the only fault, in my opinion. The hardware is bright plated, in time I do expect rust, but stainless hardware would severely impact the price point. Cheap work gloves are included to avoid cuts during assembly, and a bonus package of garden stakes, lattice connectors and planting markers is included...a nice touch. All in all, a good deal!
