I really like how easy it was to set up, configure my server software at first glance! The tooling provided by tellulive could be improved in some aspects (e.g., auto-configuration). Also, there are many things you have to do manually that should not be necessary anymore - e.g., setting IP addresses & ports etc.). But overall this product works perfectly fine so far. We've been using their free version since November 2016, we're now looking forward into paying them as they offer more features than our needs right now. Connectivity between devices via API's or other means.
