Well worth the price
Pulled air filter to recharge a/c in my 2007 Saab, only to wind up with engine misfiring and check engine light steady on. Put the BlueDriver OBD2 on, read and cleared the code, and it purrs again like a kitten. Great device - has easily saved me several times its price in costly and inconvenient visits to the mechanic for diagnostics on issues that are easily remedied.
