I have a few things from the Memory Dock Cargo Collection and love it all! I can't wait to get more!
This vertical paper file is pretty awesome and easy to use. I've got some patterned paper in mine...and have it on the shelf. When I need to find a sheet, I just pull it out (it's even got a pull on the front of it) and quickly thumb through the papers. I think that this may be a better option than those really big paper holders where you lay the paper flat on multiple shelves. This is certainly more compact and comes in pretty colors - and makes your craft space look less like a paper store.
Quality-wise, I'd say that this is decent for the money. It's fairly sturdy and the corner are reinforced...just don't turn it sideways and stack heavy stuff on it (like somebody did with mine recently when we moved). The metal edges *can* bend if you make that kind of mistake. However, I'd say that most people aren't going to be doing that with their paper file. =-D
