I was hesitant about coming to this site after all the bad Yelp reviews. I decided that I would try it anyway since there were no recent reviews and that perhaps the only postings were from dissatisfied customers who were not happy with EVDI (and not any from people who were happy with EVDI). I was glad I did! The front desk personnel were extremely helpful and courteous. I was taken in for my exam right on the scheduled time and left 20 minutes later. The technician was very professional and friendly and she explained the procedures thoroughly and answered all my questions. I definitely will use EVDI again!
