11/29/2023 - I have read so many books around technology (MCSE certified) and this is BY FAR better than anything I read before. It is so easy to understand and read. It is as if the author card about me, the reader, and how I absorb the information. Everything makes so much sense! And it is just the right amount of repetitive (for the exam). It flows! It just flows from topic to topic. I love it. I wish this author was still alive and would have written more books. God rest his soul. I will add to this review once I take the exam in a few days. I passed the exam! This book is amazing! I passed on my first try! Yes!

Nice feel

Color: Matte Silver

Feels good in the hand. It has some weight to it. I like the fact you can change out the blades. Way better than the cheap plastic disposable razors.
