Query: Good quality Good price

This code reader has worked perfectly. After spending over $1000.00 on repairs to my vehicle that did not fix the problem I attached the code reader myself and it told me where the problem was. I then took it back to the dealer and instructed them exactly what was wrong. They then fixed the problem for $125.00. Never again will I take a vehicle to be repaired before using the code reader!!
