Review on iSaddle WiFi Wireless OBD2 Auto Scanner: Engine Light Check & CAN-Bus Diagnostic Tool for Windows, Android, iOS Devices by Nick Garrett

I've already bought three of these. I bought one for personal use and used it to read and clear codes on my friends cars. A friend wanted it so bad he paid me for it (he's not a Prime member). I quickly ordered a replacement but found he was unwilling to communicate. I sent it back as defective. Ordered another one and it works just like the first one - EXCELLENT! For the price it works fantastic! I use it in conjunction with the "Torque Pro" app that comes with Android. Currently I use both to monitor my DPF temperature and exhaust on my diesel truck. $14 for it, $6 for the app, and the phone is kind of free since I already use it for other things. $20 is a lot cheaper than $200 or more for Edge Insight or other code readers! Just food for thought! Good product!
