What Customers Are Saying
Customers are divided on this diagnostic tool. Many praise its affordability, ease of use, and ability to read codes, clear check engine lights, and display live engine data without requiring a smartphone—helping them avoid costly repairs. However, a substantial group reports serious frustration with software updates and registration, citing serial number validation errors, broken download links, and Windows-only support that leaves other users stranded. Some note build quality feels cheap, with USB connection issues and small display text. Despite strong capabilities, unresolved software problems have led several customers to regret their purchase.

Useless reader.
Would Not RecommendCannot find updates, as so many others, I see. Why do we need a special report number from you before we can contact the people that can provide the update? Is it top secret? Please show me the way to get the upgrade.

Works like a dream
Would RecommendI did look at the reviews as it has bad ratings but decided to take the chance, someone stated it doesn't service jeeps. And I used it on my jeep no problem.

Open the craftsman updated app once downloaded and plug in the obd2 reader and click update on the scanner itself and once its fi...
