It works perfectly, even for real-time information, I don't know why they mention in the comments that it doesn't work. I use it with Xiaomi Redmi 9 Pro and it shows me everything in real-time. It connects easily, but you should buy the apps if you want accurate results. I recommend Torque Pro (€3.5 lifetime) for measurements and car scanner (€5 lifetime) for issues. I tried it on my Sym jet X 125 motorcycle and it worked flawlessly, as well as on 5-6 cars.
However, if you want accurate measurements, you will need to adjust the speed with the multiplier to match your car's dashboard, and input the exact weight of your car.
I also bought the corresponding wifi version, which had better reviews, but I couldn't connect it to my phone.
Attention, do not buy it!! It causes problems in many cars. I installed it in a Fiat Punto 10' and it worked fine, but after 4-5 months, it started causing issues with the car's brain (the ABS, brake, and central locking lights would turn on by themselves, and the headlights would also turn on). It got to the point where the car wouldn't move forward. I removed the OBD and threw it in the trash. Luckily, I removed the battery and reset the brain, and everything was fine. Be careful with such products.
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..
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.
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 I couldn't find a program that works at least. Torque doesn't cooperate properly. None of the ones I tried display a list of errors. I imagine it's not the device's fault, but the programs.
The test was done on a Skoda Fabia mk1
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.
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!
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!!
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€.
My car is not on the list of supported vehicles, so it does not work properly. Bad product, it should specify which cars it can "read". It does not support my Golf IV.
It works as it should without any problem. I have had it for 3 months and I have installed it in three cars (Toyota, Mercedes, and Skoda) and it worked perfectly in all of them
In the 2007 Skoda Octavia 5 RS, it worked perfectly in conjunction with the car scanner with Bluetooth. It read the faults and successfully cleared them.
It was tested on a seat ibiza 2001 (6k1). With the free application, car scanner, it connected immediately (via bluetooth) and worked perfectly. Everything is good. I recommend it.
