MMOBIELOBD2 Scanner Bluetooth - Car Scanner Compatible with iOS, iPhone, iPad and Android – OBD2 Car Diagnostic Tool Wireless OBD Car Code Reader – Check Engine Code Reader - Mini V2.1

Tried several apps (Android), works first time and later, same app showed connection issues. Restart phone helps, and it does work fully.

Very FunctionalIt’s easy to use and works really well. I’m pleased with how it performs, and it fits my needs perfectly.

Never worked. Checked with vehicle registration and type and it said it would but never connected. After numerous attempts at different times of day no connection 🙈

Great little helper, I just plugged the little OBD2 Dongle into the OBD2 Socket under my dash, downloaded the free Torque app onto my Samsung Smart phone, fired up the engine, paired the OBD2 unit with my phone's Bluetooth settings using the code 1234, as per the instructions that came with the dongle, The instructions came on a tiny little booklet that I had to read with a magnifier, my only niggle about the whole operation, Then hey presto, the phone sprang into life and dials and charts appeared that let me see how my car was performing, I pressed the settings button and a host of choices sprang up for me to operate, right at the top is error faults, 'great' this will give you the fault codes required to find cause for the engine fault light on my dash, and the two codes came up telling me I had bulbs fitted to the car in the reverse light and day running light needed replacement, Both of which I was able to fit, Job Jobbed, so I now have the tool I need to save me a fortune in garage bills, Thank You...

Took a bit of fiddling to get phone to connect to it but once working it works well. You are not going to get all the codes with free software but get the major ones and resets them.

Great product, easy to connect to my 2020 Mercedes CLA180, I use the 'Infocar' app on my Samsung phone and get all the reads come through.

Cheap made, not working at all

When it works it's fine, but often works intermittently.I've got two, and one will usally connect, but not the same one each time.
