It's great when you actually do want the flexibility. Not that you need anything ridiculously expensive, though. In a garage or workshop it's great because you can just put the brackets where you want and store long stuff like wood or pipes etc. But if you're just putting up shelves that you're never going to move it's less appealing. That said, I have used it in my study because I don't care how it looks and it's very strong.
