It is a stable solution, but they should make the user interface easier to understand
The solution's initial setup takes work. We have to organize multiple paths and many features. The deployment process takes less than a week. But it takes a month to complete if we want to make the solution smarter by integrating it with various devices. I rate the process as a six out of ten.
