I just bought one of these and put it together last weekend. I didn't have high expectations, but I was surprised at a couple of things. First, it was really easy to put together. I was waiting for poor construction and things not fitting together and that didn't happen. It also is a simple design... no special tools needed. Second, it is not the sturdiest unit but for what it is and the price, I think I can make it study enough for my needs. I used zip ties to hold down the shelves... and I will say that the shelves are not substantial. They are wire and thin wire at that. They just lay on the cross pipes, but the pipes are strong and it came with an extra that I ended up using to reinforce the top in the back. But I think tying the shelves down with zip ties will be sufficient. I do plan to use this outside near my big greenhouse and plan to use it to harden off seedlings. I like the idea of using the milk jugs on the bottom as I doubted I would use the bottom for much anyway. But here in the Pacific NW we get pretty strong winds so I will likely tie it to something also. All in all I am happy with the construction... again for the price. I think I paid less than $40 for it off eBay,
