It worked immediately on a 2010 Hyundai i20 and a 2015 Alfa Romeo Giulietta. It found the faults and cleared them.

WARNING: It is only compatible with Android, not with iOS, which was not mentioned in the description.
There is also a Bluetooth 4.0 version that is compatible with everything, but it is not the one that the stores had when I was looking for it.

Regarding the Bluetooth version 3.0 now, it is definitely bad or problematic:
- It appears in the Bluetooth devices, but only connects one out of five times.
- After it connects, it rarely starts communicating correctly with an application.

It definitely is not worth it, considering that when you need it, you want it to work to solve other problems, not to open new ones.

  • 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.

    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

    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!!!!!

    In the Grande Punto TJET with Bosch motronic me7.9.10, it worked flawlessly. It detected and cleared the faults. Now, it will show over time how reliable it is.

    Edit: 05/07/2023
    That's it. It worked, suddenly stopped working. No warning light comes on. Ultimately, an unreliable product. It was very good while it worked.

    I bought it for my Ford Fiesta mk7 2011 Petrol 1.4. I had a lot of difficulty connecting it to the Torgue application, it didn't connect to anything... After managing to connect it and it worked perfectly for about 15 days, suddenly one day it stopped working, no lights or anything, completely dead. I replaced it with a second one and it immediately connected, everything was fine for about a month, but today it's off again and I won't go through the replacement process again, I will try something else.

    It does what it promises, with a great advantage that it turns off (shortly after the engine is turned off) and turns back on by itself. Very important detail so that you don't need to remove/insert for applications like "Torque".

    I bought it for my 2018 Civic FK as not the cheapest solution but for something better. I chose the version with wifi as I run Torque Pro on the factory screen, so I chose the 2-WiFi communication.

    It worked well up to a point, but at some point, the car went into Safe Mode. Until I realized that the fault was the fuse, I didn't know what had happened. In the end, at the Honda diagnostic, they told me that this happened because the car detected data theft, so it entered that state. I don't know if it's the protocol(s) it has, but yes, it worked for me up to that point, and of course, I tried it again and again, so I simply didn't put it back on... maybe I'll get a more reliable one.

    Okay, it seems okay to see some turbo pressure and general information about the vehicle. Generally, it is not so practical and also does not work for fault scanning

    After exactly one year of use, the device stopped emitting wifi. I sent an email to konwei and they never replied. Eventually, I threw it in the trash. Also, be aware that in many mobile devices, because konwei is connected to wifi, you don't have access to the internet. So, it is probably more practical to buy another device with Bluetooth connectivity. Anyway, for a year, the torque worked fine, although it occasionally had some errors.

    Cheap, fast, and easy to connect, but firstly it does not support all protocols. I should note that what is mentioned in another review about connecting with both WiFi and Bluetooth is not true, this device is only for WiFi connection. Here is a screenshot showing what it covers in comparison to a more expensive (around 40€+) one that I recently bought from a non-Scrout store (with Bluetooth 4 version, vgate brand). The car scanner app for mobile phones in general is ideal for these obd2 devices. Now, regarding the sensors, it also depends on how many the car supports, but with the more expensive one, I definitely had more available. As for my car, a 2013 Yaris diesel, I cannot get any information about the DPF (for anyone interested) with the more expensive one, but it can be done with other cars.

    I use it on a Fiat Punto 1.2 2001 16V and it works great with the AlfaOBD application. Its only drawback is that if you leave it permanently connected, you have to close it and open it again when you want to use it next time. I don't know if it's related to my car, but I haven't found a way to avoid having to open and close it in order to connect next time (maybe it goes into sleep mode).

    *Of course, it is good not to leave it permanently connected, as there is even a slight chance of a short circuit and fire, it is good not to risk it. (I have seen it happen with a similar device)

    Very good, it connects with WiFi and Bluetooth, but you have to select it through the settings. Also, with the right application, you have all the parameters you need, such as the DPF completeness in diesel cars.

    I have had it for two months. In a crashed car with deployed airbags and it doesn't show any errors. No matter what car I have tried it on, it never shows any errors. It is good for displaying accelerations, RPMs, etc., but as a diagnostic tool, it doesn't do its job. It's just a joke!

    Regardless of what is stated in the description, it does NOT support all protocols, for example, not ISO14230 (KWP2000). So, I will have to return it and lose money on shipping. Whether your car is compatible or not, you need to research it (especially if you have older models) on relevant websites such as https://obdstation.com -https://www.outilsobdfacile.com/location-plug-connector-obd.php, etc., to check the compatibility. Otherwise, do not buy it because even though the videos with the Torque application and similar ones are nice, you will NOT be able to connect it to your ECU because it does not recognize it!

    After testing for a day on a Fiat Bravo Tjet, I can say that I am satisfied with the purchase. The device comes with the elm327 1.5 version. From research I did before buying, I wanted to avoid the 2.1 version as there are mainly negative reviews about its functionality on cheap Chinese clones.

    I used it with torque pro and the plugin for Fiat, and the operation was smooth. The only objection I have is that it doesn't show me the oil temperature, but this may not be supported by the vehicle's sensors. I also didn't try it for error code clearing because no errors were detected.
