Review: Cheap but Impressive - This thing is awesome! I'm impressed with it so far. It works perfectly with a Crown Vic Interceptor. Some of the reviews I've seen where it malfunctions seem like they were made by people who tried to use this device in a car with an incompatible computer system. If you have an OBD II system at least up until 2011 (my car is a 2011), it should work The device is very accurate in terms of the speedometer and tach. The moment I hooked it up, I started getting readings I didn't know my car measured, such as air intake temperature, just to name one If you want the most out of your vehicle, I highly recommend this product. Just a heads up, initial hook will take a few minutes for the device to scan and determine what kind of sytem you have. And, at least for me, to enable sleep mode, I have to keep the key in the ignition until after the countdown finishes. Then the device will reboot with the logo. After that I can take the key out and it will do another countdown until going into sleep mode. Other cars or trucks may cause it to operate differently in this regard. Oh, and not to mention as a bonus, this device and scan for and clear out engine fault codes. The device also has very good build quality, and there's a slight weight to it, still lighter than a samsung galaxy phone, for example. EDIT: I've used the device for over a week now and it still works fine. It's accurate and timely. There's no lag in any of the readouts. For the sleep mode, I discovered you can just shut the car off and take the key out. It may do the countdown and reboot a few times, but it will eventually just go into sleep mode without you having to do anything else. Also, I did order an extra phone holder as the double-sided tape on the devices stand is not strong enough to hold up on a window for too long. This is a minor inconvenience compared to the overall quality of the product
Review: Great way to show important ECU info on a car with a minimal dash display - My wife drives a Chevy Sonic that has one of those terrible displays that shows very little live ECU data. A previous owner had chipped out the check engine and oil pressure lights from the dash, so an oil consumption issue (poorly engineered engine) caused it to run down to a half quart of oil and fry the piston rings. I tore apart the dash and discovered the chipped out diodes, and replaced the dash. It still didn't have much info. I replaced the engine (my wife loves the car) and apparently didn't connect a coolant hose to the heater core correctly. It was probably driven 150 miles until the hose popped off and sprayed coolant all over the engine. Thankfully, I pulled up to a stoplight and saw the steam. I probably wouldn't have noticed it if I was driving and it was blowing under the car. I would have had no idea that the engine was heating up until the check engine light popped on, because it didn't have a temperature gauge. This device not only gives a live display of the coolant temp (and multiple other data feeds), but you can set an alarm to go off if a data stream exceeds a set value. It should not be a needed device, as the car manufacture should make a dash that displays this useful data, but this little thing works quite well. The alarm gives me peace of mind that my wife should catch issues before they become drastic, and the live data readout is nice for when I am working on or diagnosing problems. It saves me having to bring my code reader from my other vehicle. All-in-all, this device is a great value. 2 YEAR UPDATE This thing still works great. It is able to read OBD II codes, but won't clear them. I've only tried it on one car, so it may be related to the make/model. If I need to, I just use my code reader to clear a code. For live data display, it works great. It turns on and off with the car and provides a good display for helpful data.

### ⭐⭐⭐⭐ Poor build quality but still useful
*by J***Y on March 20, 2021*

On my 2002 Silverado it hooked up and worked well for a little while right out of the box...the tach was accurate and responsive, temp was accurate as were trip and speedometer. But hit one bump and the instrument face developed a black box in center of screen and then the RPM values went all wonky...had to be reset every minute or so, something internal seems to have been poorly soldered or some such. It CAN be switched from metric to english temps and mph, others say it can't but mine could. As a functioning plug-and-play gauge it's not very useful to me BUT...when you dig into it's ability to read the data stream then it gets useful. It reads O2 sensor voltages, airflow volume and temps, tps and a few other things that are really nice to be able to monitor. My vehicle had no codes to read or reset but this ought to be able to do both so that's a potential plus. I'm sending mine back to see if I can get lucky with a better built unit because the design concept is excellent but I'm not holding my breath. Long and short...as a functional reliable gauge for daily driving I think it's junk but as a diagnostic tool I think it's not bad so buyer beware and good luck. Weeks later....this thing seems to work fine in my 2003 Grand Marquis. This car has no tach so I tried the obd2 gauge again on the Merc and damn but it works very well....zero issues. It has read and cleared 2 codes just today...both were legit codes and I know what caused them, it does not have the "black box of shit" overlaying the tach like it did in the Silverado. The tach has no latency issues, it reads mph within 1mph of the dash gauge, temp seems reasonably accurate so I have to say ...... this gauge seems to work well on some vehicles, less well on others. In my Mercury, it's a keeper. a week later....it still works....go figure. I guess it likes some vehicles more than others. 18 months later...it's still a little twitchy but it's still doing it's job in my daily driver...2003 Grand Marquis. It still reboots at random times and sends a warning beep for no apparent reason but it also does a good job of monitoring RPM, speed, temp, timing and voltage...I'm used to the hiccups and I've come to rely on it a lot...so for my application I'd give it a 4.5
