"Works better than the expensive scanner that costs thousands of dollars. It scanned my car's issues more in detail and am glad that I bought it."

Francisco V

Stellar experience!

"Right off the bat, I was quite impressed. I plugged it into the Toyota and immediately identified that a wiring issue was causing the SRS light to illuminate. I was able to diagnose the problem and even had a query, to which I received an email response within 24 hours."

Kayla P.
