Barry:
Your WiFi Companion is indispensable. I purchased the previous 3 editions, and have found your books authoritative, informative, practical and fun. Your step-by-step instructions on downloading and upgrading were especially helpful to me. My major wish is that the loader program was Apple OS compatible.
The Companion is a welcome PDF download to my iPad, and especially a great ebook to have on hand when I am frequently mobile. I find the iPhone 7 Plus larger screen the ideal control platform when running my DCS layout.
Anyone running DCS, and now the Premium WiFi system is missing a lot of its options and potential if they do not have your books.
Very well done!
Once mastered, how could model railroading ever get more fun?
