I was debating between this unit and another similar one. I chose this because, from the images, the sheet metal looked thicker. Once received, I was surprised to find that the body was fully pre-assembled (welded). Attaching wheels and handle was very easy. 

It may seem "wobbly" when its empty but that's because it's narrow and heavy. Recommend to place heavier items on bottom to stabilize it a bit. (I put spare dish soap bottles and a box of dishwasher powder)
