Has anyone used this and if so is it worth getting. Thinking of it just to get an idea of the battery life.
Get techstream and the cable that goes with it. The real deal for diagnostics.....the same thing the dealership uses and under $50 on ebay..... it uses your laptop and usb
Do you mean OBDLink MX+? I have the OBDLink LX (which is Android only) and it works well for me with all app that I have tried including Dr. Prius, Hybrid Assistant and Torque lite.
