There are a lot of LinkedIn tools popping up these days. Closely is the slickest and cleanest I have seen in a while. It is not overwhelming and it gets straight to the point and down to business. I showed people how to pick up 500 quick leads in a matter of mins using this tool. Here is a perfect use case right here. https://youtu.be/KCytwsLkJMk

Pros:
-Ease of Use
-Tech Support is Awesome

Cons:
-Everything is not ready just yet (but they are on the way)
