It detects all faults in Suzuki Swift diesel and clears them. Fast and uninterrupted connection with iPhone!

Better than I expected. I chose it because it was the cheapest and as a simple OBD2 adapter it does what you expect well. It also has an On/Off switch but if you leave it on, it turns off by itself when not in use. I have it connected in the car and I have forgotten it there.

Difficulties with connection and reading. It does not work with the company's software, but it does work with Torque, although not as one would expect

Hyundai i20 cdri 1.1 07/2014 - It showed me the data exactly the same as Hyundai's diagnostic from two different dealerships

It worked just fine on an Opel Astra G 1.400cc model 2000 (models up to 2002 use the KWP2000 protocol which another device I had did not support) with a bluetooth connection to a Xiaomi Redmi Note 14 Pro 5G phone. I started the engine, pressed On on the device and it read the faults perfectly and saved them in a text file on the phone so I could check them later at my convenience. I used the app recommended in the manual and before connecting you need to select which car you have so it can try specific communication protocols. The 3 little LEDs it has to show what function it’s performing are not visible from an angle, you have to be directly above the device so don’t worry if you think they’re not on. I didn’t try to erase fault codes or use other functions, I only wanted it for reading and I also don’t intend to leave it permanently attached because I don’t trust them and they could short-circuit the ECU + anyway the cover that gives access to the port can’t close with it in place.

It does its job. It works with Car Scanner and Torque Pro, but I wasn't able to connect it with Carista.

It does not work on mine (Nissan Navara D40). I have downloaded three or four different apps on my phone but this one seems not to work.

Good diagnostic tool for emergencies or for checking information. The only negative is that on a Citroen C3 1.6 e hdi 2012 it constantly shows the oil temperature as -40 degrees. At least it read the start-stop accumulator code P1A9C, which other cheap OBDs did not show.

The positive thing is that I managed to connect it with Car Scanner and see faults and general information from the car. The bad thing is that it broke down in less than a month. I had it permanently plugged into the car and whenever I wanted to check something I would connect with my phone, but while I was checking the faults it suddenly died. At least it was cheap but I won't buy it again.

With the MAXOBD app, if you download it as stated in the manual, it works P E R F E C T L Y. It comes with several plugs; in my case, it connected to the engine (Honda CBR650R 2025) and read the code that had a warning light and I didn't know what it was. My anxiety went away because it was just the catalyst and I reset it. I wish I could give more than 10.

In Opel Astra H 2006 it didn't even connect. In general, it gave me a message that it's cheap for this. It's not the original, that is. Enough already, I'm moving on to devices that have the screen and the program built in.

Very good for its price, it does what it says, there is a small delay in reading the values in real time, and it's a bit strange to connect for the first time, in my case with a 2016 Opel Corsa it worked with Bluetooth not 4.0 and CAN 11, but this depends on the model and the brand.

It connects normally and works properly. VW Polo 2016.
Car scanner app, the purchase of the Pro version is also worth it.

Excellent. Immediate connection via bluetooth with iPhone. Used in a 2002 SEAT Cordoba. Detects and clears errors. Attention, it does not fix the fault. It simply tells you where the fault is and turns off the engine light on the dashboard. The car scanner app used, even in its free version, does not have annoying ads and can also display other indications of the car such as speed, engine RPM, water temperature, etc.

Very good, it detected errors in the ABS on an Opel Astra H along with a free app from the Playstore "car scanner"

In the Captur 1 diesel, it works perfectly and in conjunction with the car scanner app, I can see all the sensors live... and ash in the DPF

Easy connection with the mobile.. works flawlessly for a long time! I have it permanently plugged into the car's OBD port

Just after 5 days, while it was working normally, it never connected again either with the phone or with the car's screen....

I have used it on an Auris 2010. Even though it works fine most of the time and can read and reset codes, sometimes it can drive the canbus crazy and produces multiple faulty codes, which are not correct.

Ok, it connects easily, communicates with all the apps I found, BUT it doesn't communicate well with the car (Terios2). Specifically, it cannot read an error in the pretensioner that other (expensive) diagnostic tools can read.
Edit 23/7/25:
Today it burned out after a total of 10-15 uses. When pressing ON, its lights do not stay on and it is no longer detected via bluetooth.

It worked fine for a day, connected quickly to iOS. It stopped turning on the next day and now it simply doesn't work.

There is absolutely no difference from other MUCH more expensive ones that I have tried other than the slightly greater difficulty in putting it in and taking it out. Additionally, it also offers the on-off option with a button so that you can leave it plugged in without drawing power from the battery.

It works great with torque pro. Just the lights are dim and you can't easily see if you opened it.

Very reliable product, I have turned off every check that turns on and it connects easily with the application it provides you, even its price is worth it!

Reads data and clears faults. Ford Focus mk2 1.6 Ti-VCT. Excellent for its price and convenient to have it in the car's glove compartment.

To read data from the brain (such as turbine pressure/catalyst temperature/water temperature), which I have tested so far with the torque pro application on a Peugeot 208, it works fine. I haven't tried to clear any errors yet to test further, but so far it's working great.
For some reason, it doesn't read the oil temperature, but it might be the fault of the application. I will try others and come back.

It's a waste of money... I ordered it thinking it was good and didn't check the comments earlier. But as soon as I received it, it didn't work on three different cars... It's a waste of effort, waste of time, and waste of money... Don't buy anything from this specific store again and do your research before making any purchases, especially reading the comments

It worked flawlessly with the Car Scanner ELM OBD2 and Golf V and Polo TSI 1.2.
You need to select Bluetooth LE (4.0) to connect.

The only positive thing about this product, and the 1 star, is that it clears the check engine.... I have replaced 2 items that suddenly burn on their own and never turn on again... I would not recommend it to anyone!!!!!

Fast service, small and convenient, immediate connection with mobile, with 4 applications that I have worked flawlessly, the only thing I don't see is when it is open or closed
