There are no downsides to using this product, it has been very easy for my employees to use as well! It's so much easier than keeping track of everything in our email or Google calendars! This makes life simpler when you have multiple people working with your business/company at once. I would recommend trying out the free trial first if possible because there might be some features that aren't available yet but they will add those more functions over time. They've made things so simple by adding such great tools to help us organize all aspects of what we do within one place. The only thing i dislike about kin is their monthly subscription fees which can get expensive especially if you're not sure how many users you'll need (but then again maybe its worth paying for?). We like being able to send each other notifications via emails instead of having to go into another app just to see who was doing something important.
