Clear and Concise
Preparing for my ENRSI, I am a visual learner and learn best from examples. I like that I can follow along using CML/GNS3 to understand the basics and mechanics, then try to build a more difficult lab. Everything so far has been clear and concise.

The experience has been very beneficial; their team is friendly and helpful, and I've learned a lot from them.
