What do I think about the scalability of the solution?
K2-Series is scalable.
How are customer service and support?
Palo Alto offers two different types of support - partner-enabled and direct. The direct support is a bit expensive because it allows customers to open cases directly with Palo Alto techs. In contrast, the partner-enabled support goes to the ticket distributor, which can be time-consuming. In general, it can be hard to get answers from Palo Alto's support.
How was the initial setup?
The initial setup of the firewall was easy and took between five and ten minutes. However, implementing DNS or IoT security or packing working features requires assistance from an integrator or professional service.

If you compare K2-Series' quality with its price, I think it is reasonable.
What other advice do I have?
I would rate K2-Series nine out of ten.
