The assembly manual is a wordless workshop. Give extreme attention to detail, especially where the small parts go. Like me, you might think: "There are parts missing..." No, probably not. Just read the manual carefully where the small parts are going (e.g. the middle hinge). Once assembled this is a very convenient lock box. As you see from the pics, I keep mine on a couple of tires to keep it above the dirt. (I don't have a deck.) The first time I saw one like this was a 170 gallon box at Costco, but for a lot more. At just 20 gallons less - and without the membership fee - Walmart's Marketplace beat Costco on lock boxes. As you see I'm not even using the full 150 gallons for me stuff. The only problem I find is the off kilter lid upon closing; I believe this happens because it's not on a perfectly flat surface, but that's easily compensated. This is an excellent deal.
