CCIE
A friend of mine purchased Workbooks 1 - 4. After he completed a lab we would go through them together. While I primarily used another vendor, INE gave me another perspective of what to study for the CCIE. It helped me pass my CCIE the first time. And many times surprised me by level of detail your solution guides covered. So thank you for putting out a quality product!
