Review on ATDIAG OBD2 Scanner: Enhanced Universal Car Code Reader - Diagnostic Scan Tool for All OBD II Protocol Vehicles Since 1996 by Moe Gilbert

Should have bought this sooner. Of course, it's only recently that I've seen a number of check engine lights come on on my vehicles. I first paid $89 at a local store to have the codes read. I saw this and decided to give it a try. I have used Turque (Lite) to read and erase codes. In the last few weeks I have read two codes and replaced three sensors. I saved hundreds of dollars by buying a part from Revain and replacing it myself. Great product and worth $15. UPDATE: I lost my first purchase so I bought a second one. I can't get the second one to work. Only shows "connecting" but never actually connects. Rating downgraded from 5 stars to 2. UPDATE 2: 7/25/18 - Rating upgraded to 5 stars again. The problem was with my phone. I put my phone in airplane mode, connected to wifi OBD and it worked. Apparently, some applications started conflicting with IP address or OBD WiFi port.
