It takes a long time to assemble by yourself. The supplied L-shaped screwdriver is difficult to use, so I recommend using a tool you are familiar with at home. It is better to use work gloves or gloves. Also, the bag containing the parts has letters written on it, but some of the letters are faded and hard to read. In step 15 of the assembly process, you put the parts for attaching the shelves into the holes, but I don't know if the holes in the shelves weren't properly opened, but there were several holes where the M parts didn't go all the way in. Since it was the height where I wanted to install the shelves, I was able to install the shelves even though they didn't go all the way in, so I'll use it as it is for now. The casters feel a little clunky, but I don't think I'll be moving them around except when I'm cleaning, so I don't think it'll be a problem. In this way, I thought that the product had some rough spots. As for storage, it's more solid than I thought, so I think it's sufficient. It looks like you can store a lot of things neatly in the boxes that are sold separately.
