Just my opinion - I think a real socket set and a set of cheap wrenches would be a better option.
If you can post a budget, or what you'd be willing to spend - more help or other options can be provided.. if you already have wrenches and sockets, is there something in that kit that makes it MORE attractive to you?
I think a lot of people would view that set as "gimmicky". Small universal tool sets are usually not real good at doing many things.
