This is a great shelving and storage unit. The product came well packaged in the box. Was super easy to put together. I did it myself, as a woman, and in mere minutes. I did not need any tools to put it together, however, I did use a hammer to secure it and to make sure everything was securely in place. I am using it in my garage to store food and water. I am not utilizing it to its fullest advantage with the weight limit on each shelf but it could easily hold what it says it's capable of. This is a very sturdy unit. I will definitely be ordering more of these for a complete garage organizing project.
