So far no luck with the product and support...Review by Vincent
I have purchased this unit from Amazon.com but it cannot communicate my Honda Civic EX 2004 and Acura MDX 2001 cars. To add to that there is not live customer support but have to depend on forum. Really after paying $125??? doesn't make any sense...

RESPONSE: We purposefully handle all tech support from our forum because we find this to be more valuable. Customers may have similar questions and may want access to answers immediately, rather than waiting for the business to open to get one's questions answered. (Posted on 6/12/2013)
Fantastic tool, great company to deal withReview by Edward
The tool works better than I expected. Does all that was claimed. My order shipped promptly, and arrived when expected. The tool linked and started up right away. Real time data response is fast enough to be considered real time. I had to hook an on-off switch up to it since I had to unplug and replug it in to get it to restart after shutting the truck down. I will post this problem on the Scan Tool forum to see if I missed a setting but this is a very minor issue for me. Even better is the customer relations staff. I contacted the company to inform them that I was surprised to see the price of the tool drop by 75.00 the week after I purchased it. Less than a day after I e-mailed this information to them I received a response and a refund for the 75.00. But it gets better. The next day the price dropped another 25.00 and I received another response informing me that the price had dropped another 25.00 and that was also refunded to me. They also advised me to post the problem I had on their forum to receive a solution to the problem, and also make it available to all. I had already installed the switch, but I will also post to the forum to see if there is a setting to fix it and make it available to all. I would not hesitate and have already advised friends to purchase these type of tools from ScanTool. They sell a great product, and back their products up with great customer support.

Awesome tool.Review by Daniel
Works flawlessly with Android's Torque program. Works perfectly with my '08 Ford Focus and my '04 Dodge Neon. Reads codes quickly on my father's '02 Explorer and my mother '02 Impala. This thing rocks.

Painless upgradeReview by Tim

Awesome Bang for the BuckReview by kev [Amazon Review]
Looked at many different OBD2 systems. This really is the most versatile, expandable and affordable system I've found. There is customer support, and forums, updates available and more on the way. This unit compares to some really high end ones. You won't be able to flash computers as far as I can tell but if you buy the nicer programs it can do just about everything some $1500 systems will.

Well made!Review by Collin M Simmons [Amazon Review]
I bought this a few weeks ago and I haven't stopped playing with it yet! I am using the Bluetooth feature for the Torque software on a Samsung Galaxy S (Android 2.2). As soon as I plug in the scanner it goes through a startup sequence that takes all of about 10 seconds, then my phone connects to it and all of a sudden I have all the live data! No connection problems this far, it's never disconnected and I have used it for a trip that took about an hour. I love the fact that it connects through a cable that way you can plug the cable in (if the plug is in a tight location) then plug in the adapter to the cable whenever you want to use it.

Great deviceReview by Danny Lepage [Amazon Review]
Works flawlessly with 2001 Audi A4 1.8T & 2005 Ford Freestar Sport 4.2L. Bluetooth communication with a Samsung Galaxy S running Ian Hawkins' Torque application under Android 2.2 (Froyo).

Works Great!Review by J. Bell "stallfactor06" [Amazon Review]
It works great. Easy to install on my 99' Pontiac grand prix GT, and works great with my Evo 4G. Couldn't be more happier. Comes with a CD to put on your computer. Great stuff for a great price.
