OBD WIFI just works

I wanted to reset the codes and see other OBD info and this device works great. I leave it plugged in and never have issues as it goes to sleep mode automatically. With the WIFI interface I also still have all the Bluetooth functionality of my hands free for phone and streaming music from my iphone over bluetooth. Great addition to my gadget collection and since it saves my settings only have to use one for all my cars. The guage function is very cool. Will buy the extended software to get the additional brand specific codes as well. Thank you for a great purchase!

It helps my head not to hurt

I looked a bunch of other diagnostic scanners and apps and settled on this one. I’ve had it for several years, it hasn’t let me down, it’s saved me a ton of money, and the features just keep getting better.
If something pops up wrong on my truck, that I’m unfamiliar with, a bit of research on the web clears things up.
So, this tool, paired with a good service manual, will get me in the ballpark. If I can’t do the job, at least I’ll know enough that someone’s not going to screw me, when I take it to the shop.
Thank you, and keep up the good work!


Could use some work

I find that under monitor Emission readiness does not update in real time. I would to go back to diagnostics the back to monitor in order to determine if the vehicle is ready for the Emission test. It is frustrating having to pull over on the highway to see if the vehicle is ready.
