Amazing product, I have 4 of them, everyone needs one of these!

Amazing product, I have 4 of them, everyone needs one of these!
I've had an UltraGauge in my off-road tacoma for over 5 years now. It is such a useful and simple device, it has cleared and checked hundreds of codes (no exaggeration, my truck is heavily modified and gets grumpy often) and it has helped me diagnose problems on all 3 of my vehicles.I finally said to heck with transferring my one Ultra Gauge between 3 cars, and just bought 3 new units. My understanding is that these have new firmware/software to give even more features than I previously had.I would recommend these to anyone, even with a bone stock car. Helps you get insight to how hot your car/truck is really running, how long the engine has been on since start, battery voltage, boost PSI, fuel rail PSI... nearly anything your car measures, this little device can display.10/10 would recommend to anyone, and no they didn't pay me. I paid them! 4 times!

5.0 out of 5 stars Great , useful, simple guage
Reviewed in the United States on March 21, 2019
Great guage all the way around. Little weird to get going how you want at first but once you get it its easy. If you have troubles theres a very helpful video on youtube of a guy in a jetta. At first i thought mine wasnt turning off when i turned my car off but just takes like 30 seconds. If your ever like "what is going on" just unplug it. Lol . sucks only comes with a velcro mount considering thats failry permanent in a sense. What i did was bought a cheap gopro windshield mount and couple sticky pieces and made it work. Not so permanent but works well looks good.
