Based on your experience (or your thoughts), what are the advantages (and any major disadvantages) of using the Shipping Label Integration feature? Thank you.

I'm about to start using Shipping Label Integration. I think it's good because it's all integrated and it looks that I can do a lot of things. I'm starting to implement it today, I will know in the next few days

Thanks, man! Any bottleneck so far if you have used it already?
