The stability of the solution's router is its most valuable feature.
What needs improvement?
The configuration needs improvement. Most routers, like HP or Aruba, use a UI interface. Those solutions are similar and uniform. It's easier for us compared to Cisco because with Cisco you are not using normal commands. They need to enhance the UI to make it more usable.
Which solution did I use previously and why did I switch?
I didn't previously use a different solution.
What other advice do I have?
I'd recommend the solution. Once you plug it in, you can basically forget about it because there are never any issues. It just works, and that's great. I'd rate it ten out of ten.
