I hope this won't come out harsher than I intend to, but I'm so tired to hear this expression "not reinventing the wheel" to justify using third party code. This is not what it means.
Note that there is not a single wheel that was built once in prehistory and now every human gets it lent when they need it. People build wheels everyday to fit their needs, reusing the concept of wheel, that is, knowing that a circular object allows for smooth movements with less friction. The analogy in software development means that you've better know of designs that help you solve your problem, not that you should blindly use code built by someone else to bypass the whole problem solving. This is basically trying to use a bicycle wheel for everything. This may work well on an other bicycle, not on a car.
