WOW what can I say. I took the 5 day course the second week of December and as soon as I got back to my stores I was doing repairs. I didn’t relize how much I actually learned until I sat down and I opened my first phone. WOW I knew what I was doing 🙂 Dinyo and Luvia are great and make you feel at home as soon as you show up. If you are thinking of doing repairs you need to take this class. It has already paid for itself for me in less then 4 weeks.
