Great class, Lluvia (Uvie) was a great instructor. I learned so much from her in just 5 days (which went by very fast). I was doing small repairs already, but after this class I have the ability to do major repairs and leave the competition behind. A big Thank you to Lluvia who was very knowledgeable in the field. She had a detailed answer to all of our questions. This class/certification is worth the cost and is a good investment if you want to be in the cellphone repair industry.
