Honestly I have never cracked opened a cell phone before in my life but I left the training center with confident and felt like a pro after my 5 Full days with my favorite “Lluvia.” You threw in all the important and must know topics one after another to learn and to take notes. You are a truly super experienced technician and master in all mobile products. Thank you so much for your time and patience on us.. Thank you (Twice) 🙂
