Bests & Worsts Reviews from Amazon

I am a ASE certified mechanic and Wyo Tech grad. I worked on my friends and family car on the side. (most of the time for free) I used this on my 2006 Chevy Silverado that just recently had a check engine light code. I have tested it on 2004 Volvo V70, 2007 Ford F150, 2015 Subaru Outback and 2010 VW Jetta. It was really easy to use. I use it off my Iphone 6. I downloaded OBDCarDoctor from the apple store. Plug in the Foseal Scan Tool. Turn the ignition on (doesn't need to the running). Went to setting on Iphone, then hit Wi-Fi. Found Foseal came up as a Wifi network and link on. Opened OBDCarDoctor App and connected right away. Found my code and a brief description about the code. Trouble shoot the issue, Cleared the code. Very happy with the results of this product. Came with instruction of 3 possible apps that will work for your android or iphone/ipad. BTW "DashCommand" for 10 bucks is a very powerful, award winning program. The other free apps are great for reading engine codes/clearing and on time engine rpm, temp, oil pressure, etc... I did end up buying the DashCommand App. Well worth it to me. The apps update as the years go by for free I like these types of scanners better than the handheld ones. Once you buy a handheld scanner (for more money) you get the lasted of updates but then as the year or years roll by its out of date. If I work on a friends brand new 2017 car, I would need to buy a new handheld scanner or pay more money for a update again.
