By Juraj · Last updated: June 2, 2026 Home The Thinkscan 672 is the cheaper little brother of the famous 689BT, and the only real thing it drops is ECU coding.

Carly OBD Review: The Biggest Scam in the OBD2 Scanner Industry
By Juraj · Last updated: June 3, 2026 Home I bought Carly OBD twice, tested it on multiple real cars, and made a viral video taking it apart. My verdict is the simplest I’ve ever written: don’t buy it. Not for diagnostics, not for used-car checks, not even for coding. It’s an overpriced locked dongle…
