I have not bought one, but have looked at them at the store. If I was going to buy a box for at home, I wouldn't hesitate to buy one of them. I don't know how they would hold up in a shop environment, where the drawers are opened so many times a day, but they should last at home pretty good. For the money, I don't see how you could go wrong.
Even in a shop, if I was starting out, I may consider it. The difference in cost of tool boxes will buy alot of tools. In a shop, you don't make money with the box, it's the tools in it that make the money.
Look at it like a "gold plated Jug" verses a glass jar for holding change. The contents are worth the same amount, no matter what they are in.
