AWESOME scanner, great value!

“This scanner did wonders for me. I was a bit iffy about getting a scanner that works thru Bluetooth, as pairing can be a bit tricky for bluetooth scanners. But this one was a breeze to pair.”

Excellent device for diagnosing vehicle problems.

“It's so convenient compared to other OBD II readers that only give you codes that then must be referenced in a book.”
