I bought it experimentally, it doesn't read every type of fault (you could say, well, it only costs 5 euros). It reads the basic diagnoses that a vehicle gives to some extent. It deletes most data normally, very frequent disconnections...

Very good but ONLY for checking and clearing a check engine light. It doesn't read many sensors. I was forced to buy another model of the ELM 327 with an HS MS switch that connects wired to the car with a laptop and I run it with Forscan which reads many sensors throughout the car.

kia rio 2008, it found exactly the problem and exactly which cylinder.
With the obd Mary app in the full version, it's worth it and most importantly it's in Greek.

I got 2 pieces and I use them with the car scanner app with the blue check symbol. So far it works just fine and one of the two was used every day by my daughter to read and clear a specific error until she took it to the garage.

Connected easily with both the car and the two apps I have (torque and OBDocker). Limited capabilities possibly due to the car's restrictions (in many functions, my apps report that the system does not allow their modification). So, I don't know if the issue is with the stick or the car's software, hence the 4 stars.

When I installed it, the car had some issues with the brakes and refused to start. Until I used another OBD2 reader and cleared the DTCs

It worked perfectly with the car scanner app; it requires proper settings in the app regarding what Bluetooth version the device is

Mitsubishi Space Star 2016. It doesn't work, warning lights are on the dashboard. Another scanner I tried works, though. Maybe this one doesn't work for my car

Used on OPEL INSIGNIA. Connected without any problem and its diagnosis was accurate. However, when I started the vehicle to get diagnostics while it was moving and then turned off the engine and disconnected the Scanner, I found that the car was blocked and wouldn't start. I disconnected the battery terminals and restarted it, and since then I haven't used it. Good only for initial diagnosis without the vehicle running

Everything is great and affordable... This is the second product I bought along with another one for certainty and testing... I tried it with OBD Mary & car scanner... The application provides various information, some of which show okay and others do not... I wanted to read error codes and erase them along with the warning light... And the job was done... Essentially, the fault codes were due to a poor cable connection and not real... However, I was puzzled during the tests that it shows catalyst and lambda fail while it shows the lambda voltage, okay.... The pairing usually happens through the application and not from the device.. If it asks for a code, I think it caught 1234 for me... I don't remember well... Also, keep in mind that the application may ask for information about the car such as weight, etc... I found them from Carfolio..

MG ZS the OBD in combination with Torque Pro (purchased version) sees everything, even external temperature.

In the Dacia Sandero Stepway model 2022. It works perfectly. Both on the tablet and on the mobile and on the car's factory screen.

I can't set it up with my phone. I've downloaded 10 apps, none of them can find it. I don't know what I'm doing wrong. Even though it sees it via Bluetooth in the app, it doesn't show it.

Quite good for its price. I installed it in a Mazda MX5 NC (2006) model, downloaded the Torque application on my Android screen, and they worked perfectly together. I can see the available measurements/values of various engine parameters in real time. What interested me the most was being able to see the coolant temperature during the summer, and I can say that it does its job well.

I couldn't connect it to any car I tried (ford mondeo 05', suzuki vitara 17') and with any free application. In an application that I paid 5€ it connected but I couldn't delete errors, it only showed me temperatures, revs and some information.

Guys, it's great! You download a free app from the store and after connecting it to your phone, it shows everything quickly!

I have it since 2022. It has been tested with the Car Scanner app on a Duster 2017, Octavia 2010, and Forester 2011. It worked properly on all three for monitoring data from various sensors, I did not attempt error deletion. The 4 stars are due to the difficulty of connecting via Bluetooth sometimes, which could also be attributed to the application. It is a decent purchase.

As an OBD device it works, but at least I didn't find a program that does a lot. I downloaded the classic one for all OBDs and although it didn't give me clear error codes, it did reset the check engine (fuel quality issue) immediately and it didn't come back on. The Torque program, which is said to be the most accurate, doesn't work properly. None of the ones I tried display a list of errors. I imagine it's not the device's fault, but the programs. Essentially, only the corresponding program at the workshop can go into details. If you just want to clear errors so you don't have to go to the workshop for simple situations like bad fuel, then it does the job OK.
The test was done on a Skoda Fabia mk1

Very good obd. Works reliably on Opel Astra H. Connects easily with the mobile phone and clears faults normally without any issues

In a Seat Ibiza from 2002-3, I had difficulty connecting, but I eventually managed to do so after trying several programs. I didn't even use the CD because it didn't fit in the laptop due to its age.

Fast Bluetooth connection. Used with the car scanner program and has all the basic supported information provided by the car's ECU.

After first buying a wifi OBD and not connecting to anything....... I bought this one with Bluetooth connection. I connected it to my phone directly without any problem and with the car scanner, I saw the faults and cleared them without any problem. Chevrolet Laceti 1400cc. (car scanner purchased version)

Bought it in the summer of 2023. Very user-friendly, it can recognize and clear faults at a very small cost. The app I downloaded is called OBD Mary. First of all, it is in Greek and its menu is user-friendly.

It does what it says, I recommend buying the Torque application and not downloading the broken one of unknown identity that they provide when it comes to this specific OBD scanner, you will see more accurate results with the paid version. WARNING! It reads cars after 2002-2003!

Excellent response and efficiency on a 2007 VW EOS. Very good collaboration with the exceptional Torque program included in the package!

I connected it to Opel Astra H 1.4 2006.
Although it says it can connect with Bluetooth, in the end it only connected with Wi-Fi.
The result is that it says "can't connect with car ECU" so it is useless. I tried it with torque pro and car scanner.

I bought it to clear the check engine light as I knew there was no problem and it regularly turns on due to the conversion to gas. The application you download when scanning the QR code is an old, modified one that will most likely not work properly on your mobile phone and is also considered dangerous. Better spend 3.5€ and download the official one from the playstore (torque pro). Hyundai Accent connected perfectly.
P.S. The product is a Chinese imitation.

It works great and reads-clears engine error codes, in combination with the Obd Mary application that I have purchased for my Android device. It also provides a lot of information about the car, from fuel consumption to engine coolant temperature, as well as many other things. Quite a useful tool for its price!!

I cannot connect it to two mobile phones and five applications. I am writing this so that you do not lose your money like I did.

Unfortunately, although it fits in the car's socket, it cannot find a connection protocol. The application I used on my smartphone was Car Scanner Pro version. It seems to work fine, it just can't connect. Maybe the car model is too old... The 3-star rating is subjective. I wrote this review to prevent those who own a Toyota Yaris 1999 1.3L from buying it for nothing. Fortunately, its value was only 5€.
