The software has been very easy for me to learn as I have had experience with Cisco switches in my previous job but am new at this level of network engineering/management so it was great having someone who could walk through things step by step! It's not really anything about netvisor itself - everything seems pretty good from what we've seen thus far.
There are no problems or issues yet regarding its use within our organization. We're using NetVisor primarily because of all of the benefits provided such as being able to create VLANs easily without needing any additional equipment which makes life easier when you need to quickly setup networks for different departments.
