Bests & Worsts Reviews from Amazon

Absolutely excellent device. It has already saved me over $1,000. I had a repair shop telling me I needed a new transmission. I bought this scan tool, downloaded a free app (there are many), and saw that the only significant transmission code was a faulty turbine speed sensor. I replaced the sensor myself for $25 and the transmission behaves like new. I've had other bluetooth OBDII scan tools, and this is the only one that actually works. And the company stands behind it completely. I am impressed not only with the device, but also with the company, whose owner contacted me directly just to see if I was satisfied. I am.
