I like that it is intuitive to install in your environment with no hassles or problems when setting up an agent for installation; also works well once set-up allowing all devices connected access at one time without fail/failure modes (which can be problematic).
It would help if you had more information about how many agents are running so users get notified they have reached their limit rather than having issues logging into apps afterwards - however this could simply mean there isn't much support yet provided by Microsoft Support as we're only just starting our implementation using MS SCCM 2013! We've been able solve some pretty serious security risks across departments within my organisation since implementing CISSSafeForWork client software from MicroSoft Solutions Catalogue team last year which includes mobile device management too through Airwatch App Manager.
