It allows you to keep track of your keys, it's easy for anyone in my team or outside employees who need access into our servers at any time - we have no issues with that! The price isn't bad either (it could be better though).
I do not like how sometimes there are some minor bugs but they're quick fixes so nothing major here really :) We use this software mostly as an internal tool where everyone can easily share their ssh/scp credentials without having them stored somewhere else which might get lost when someone leaves the organization etc..
