I'm with you there. We had a new location stand up with full Meraki. (32 MS390 switches, an MS425 Agg switch, an MX250 soon to be 2, 33 MR56 APs).
It was kind of a test for us to see if we could replace most of our Cisco with Meraki. We just worked through a QoS/SMB file transfer issue that would determine if we go full Meraki throughout. That test was successful, only because the Meraki support keeps us up to date, and is more than willing to work with us at any point. So even if the product isn't 100% ready for prime time (which I do believe we are currently in that situation), I can still justify moving forward with them due to the support that we have received, and continue to receive.
I'm fairly excited for what the future holds for Meraki, especially with the new addition of the sensors and cameras. Just have faith, Meraki will take care of you.
