Does exactly what I needed it to do

I purchased this a couple of months ago to be able to read OBDII information from my 2008 Jaguar, I have a $60.00 "code reader" and it gives just the basics (DTC codes and the ability to clear/reset them). I wanted a little more technical information (serious diagnostic information). I downloaded the Andriod compatible app TORQUE (the $4.95 Payware version) from Google Play, installed it on my Galaxy G5, plugged the OBD2 OBDII Bluetooth for Android Devices into the Jag's OBD port, paired it via Bluetooth, and HOLLY SMOKES! The detail of the information available is staggering! The negative reviews here? I'll chalk them up to "Buyer Stoopidity". For $10.00; I'm buying another one!

Works with Mygreenvolt app!

I was looking for an OBDII reader to use with the "mygreenvolt" app and my gen 2 (2017) Chevy Volt. I plugged this very reasonably priced Mestart OBDII reader into the OBDII port on the Volt, located to the LEFT* of the steering wheel, searched for new bluetooth devices on my phone, and figured - rightly - that the one that said "OBD" must be the one I was looking for. Most bluetooth pairing codes these days are either "1 2 3 4" or "0 0 0 0". I tried "1 2 3 4" and that worked. As soon as it was paired I opened up the app and it too worked. Awesome! *Be sure to use the OBDII port to the LEFT of the steering column. The similar looking port on the right side of the steering wheel in the Chevy Volt is for something else, and will NOT work with an OBDII reader.

Using the provided app for the phone it did seem to provide some useful information towards the diagnosis - using it every time ...

Got this to diagnose issues on a Land Rover Discovery as well as a Mitsubishi Montero. Using the provided app for the phone it did seem to provide some useful information towards the diagnosis - using it every time they would act up instead of having to wait to take it to the shop and so often the manifestation of the symptoms would either have changed or temporarily subsided. Allowed to provide more information to the mechanic and a more effect and I think more rapid repair.

Perfect tool along with a $5 ap

This tool is more than i would ever need. I bought a $5 ap called torque and this tool connects via bluetooth...i just wanted to know what check engine codes show up but the ap and tool combined allows you see live specs including Rpm, temp, etc based on what your gauges and sensors report of course. Great tool i would buy it again.

helped me pass emissions

awesome gadget. allowed me to reset computer and know when car had accumulated just enough data to pass emissions (emission test readiness) so i could get that done before the check engine light came back on. it took a few days of driving. now i have new tabs and can work on the emission issues without stress. I used the free Torque Lite app on an android phone. I wonder how many people saying "it doesn't work" don't understand that first you have to plug it in, power on car, and then PAIR WITH IT IN BLUETOOTH SETTINGS before launching your interface app (like Torque Lite)

Worked in my GT86 with my Joying Head Unit

Product works perfectly, and with some effort it worked with my Joying head unit. Torque didn't recognize it at first but after restarting torque it found the device. EDIT: After living with it for a while I am very impressed. It instantly connects when I start torque. Any time there is an issue, it is the fault of torque, not this device. I would recommend this to anyone that wants to learn more about their car, or possibly even professionals. I'm sure they use much better equipment, but it certainly isn't as cheap as this. After setting up torque to my liking it feels like I am driving a much nicer car than I actually do. The features torque has remind me of the systems normally seen in super cars you see on top gear, so that's fun lol

Although unbelievably cheap, this is the best one.

This thing is a dream. It's the small size, so it's less likely you will break it when applying the parking brake. It communicates via bluetooth, rather than WiFi or serial port. Bluetooth is what you want, because it leaves your tablet or phone's WiFi available to simultaneously connect to the internet. Documentation on the net is sparse and laden with superstition. My buddy and I tried to make a more expensive larger "OBD dongle" work, but failed. It turned out to be a WiFi version. The apps kind of imply that you can set the device to communicate through either bluetooth or WiFi, but so far, in my experience, it ain't so. The hardware is what it is. And it's up to you to figure it out. Believe me, this can be a time-consuming and painful process when you have to be outside in the weather intermittently crawling under your dashboard to see WTF is going on with one of these dongles which, until you develop facility at establishing communications with it, you can only extract clues by trying to interpret tiny LEDs flashing through the devuce's plastic case at you. - Take it from me. Buy this one. It's inexpensive, so what risk is there? AND REMEMBER IT USES BLUETOOTH AND YOU ONLY NEED LOOK FOR IT ON YOUR HOST'S BLUETOOTH. ALSO FOLLOW THE STEPS IN THE INSTRUCTIONS VERY METICULOUSLY WHEN CONNECTING TO IT THE FIRST TIME: - Turn your car off; - Plug this OBDII dongle into the OBD socket in your car; - Start your car's engine; - Use your celephone or tablet to scan for bluetooth devices in the area. - Pair with the device named OBDII; - Use password '1234'. Once you can SEE the device as a bluetooth device, you've got it licked. Download the free android app called "Torque Lite" from the google play store to use as your first host app. Once you get this to work, you can fly on your own.

Amazing bargain

Very simple to use, plug in, start engine, pair with tablet (or phone) after downloading app. I tried Car scanner and torque light. Device transmitted flawlessly. My older OBD reader outputs a code which you then look up. This device tells you what it is, and sends sensor information on engine function to linked tablet. Info also includes ( depending on what your vehicle outputs) info such as engine temp, rpm and if moving , speed, rpm etc. The take home here is this reader is just the data sender, the software you choose does the work, but as far as sending goes this does the trick.

Very simple, very easy.

Very easy to use and got the job done very quickly. Saved me a ton of time and money identifying (and then clearing) a faulty check engine light. (CEL). Paired well with the free app I downloaded to my iPhone. Right price for the right solution. Just do your research about what the codes mean and what to do if you get a certain one. Some codes are known issues for your particular car (like mine was). So know the difference between a real problem to get checked out by a mechanic and a false code that can be reset and forgotten.

Wicked awesome

Works like a charm. Got tired of going to the parts store to read the latest code. Only trick is to open the app first (I used Torque Lite) to connect to the ECU. Once I tried connecting via the bluetooth device list like how I do with everything else and sat there pushing OBDII for minutes like an idiot before I realized what's up. Get it.
