spectacular, as my Guatemalan-Peruvian friend would say
AliExpress Shopper –
The device makes a great impression… Great price.
AliExpress Shopper –
For simple use and to eliminate harmless defects, it’s great. It also has a very beautiful design!
AliExpress Shopper –
I was sceptical, but this thing is excellent. super useful for clearing check engine lights and diagnosing issues.
l***r –
Received. Works perfectly. Connection OK.
AliExpress Shopper –
spectacular. Good service, works perfectly.
just connect to the OBD2
and downloading the Maxobd app serves as a keychain, it scans and clears codes, and you can monitor various parameters of the car in real time.
AliExpress Shopper –
Good quality product, properly secured during delivery, I recommend the seller, I may shop here again.
R***s –
Looks quality but haven’t tried it yet. everything ok, recommended seller
I***v –
correct work with OpenDiag application and LADA 2115
Works perfectly with the OpenDiag app and the VAZ 2115 injector. You need to properly configure the connection to the ECU of yours, and everything will work. I previously had it set up via a wired connection, here I just changed the connection interface.
AliExpress Shopper –
Great device for basic car diagnostics. I use it in a Mondeo MK5 to monitor DPF combustion. As described. And I managed to buy it at a promotional price. I recommend it.
AliExpress Shopper –
Bought this as an upgrade to my 6 year old kw902.
Appears to work just as well as my older one, maybe a little faster. Works fine on most fords, (with an engine).
AliExpress Shopper –
But neither the 905 nor the 906 worked for me. They only connect with the “drum” and the connection is not stable.
p***i –
It worked great and the app does the job.
I’m still looking into other, better apps which i think will just work – when i have time for it.
Two weaknesses:
1. The loop that comes with it is a bit unnecessary imo; how is it useful?
2. The on-off light indicator is too weak.
AliExpress Shopper –
Excellent
AliExpress Shopper –
It works perfectly and detects it on the first try without any problems.

Received my order in two weeks. Great quality! You can useeither with its own app or any other app. Does work with myiphone.
P***T –
Perfect
AliExpress Shopper –
It connects with several Torque app tools.
poor proprietary app.
AliExpress Shopper –
Arrived quickly. Looks like it’s of good quality. Haven’t tested it yet. The application has been installed. I recommend it.

The Huawei phone does not support the app. 🙁
AliExpress Shopper –
It works perfectly in a 2014 Lexus IS 300h.
There may be some parameters that won’t display anything, but generally it works perfectly and provides a lot of information about the vehicle.
AliExpress Shopper –
Goods arrived ok. looks good.

Works fine on my iPhone
AliExpress Shopper –
Packaged and received in a very short time i like the device is working with almost all the diagnostic apps , the software that came with didn’t recognize my car peugeot 308 phase 2 2014 , and have limited functionalities i used obd 2 facile plus app its better
AliExpress Shopper –
Very good product. dongle works fine with my car
AliExpress Shopper –

The package arrived quickly – in 10 days.
I recommend the seller.

Best price-performance ratio

Good product, fast delivery
AliExpress Shopper –
Fast delivery and well pack. download the maxbd app and try out. most of the features support but not all. well base on the money paid still acceptable.
S***G –
Ok
AliExpress Shopper –
This obd plug dosen’t read anything. it is worthless. i have a fault code that i know of and it isn’t even detecting that.this is a joke
AliExpress Shopper –
A beautiful product, and the best feature is the on/off button. Thank you very much.
P***K –
I recommend it!
AliExpress Shopper –
Works great, the lights dont come on but once you press to turn on its does, it appears on the bluetooth on the phone, bit unit less are always off. Maybe there’s a firmware update, don’t know
Android app works ok, its also compatible with other apps of your preference
AliExpress Shopper –
Very clear and convincing
AliExpress Shopper –
The official application of this product is really bad. The main features of the app don’t work, they simply crash.
AliExpress Shopper –
It is a very compact OBD device. It comes with a strap so you can transport it without it falling. Easy to connect via Bluetooth.
AliExpress Shopper –
I didn’t really like the recommended app, but it works perfectly fine with the torque app i used before. the manufacturer is not blocking any functionality and is not forcing you to use their own app and i think it’s very cool of them. dongle alone works perfectly fine, looks good and offers typical functionality of these products. for sure i will try some other things they offer.
AliExpress Shopper –
It works perfectly in a 2010 Chevy Pop and a 2013 Chevrolet Captiva. I still need to test it in my 2026 Chevrolet Captiva. I didn’t take a photo because I was too lazy, but I do recommend it along with the app they recommend on the packaging.
S***n –
Excellent quality product, the app is amazing and all works so easily; couldn’t be happier
G***7 –
Everything works properly once you understand how to connect the device to your phone, everything works great 👍

AliExpress Shopper –
Arrived within the deadline, very good product, the app is a bit limited in some functions.
AliExpress Shopper –
Thank you for the return.
AliExpress Shopper –
very practical, excellent product

I received the Konnwei KW905 Professional car scanner. Visually, the device is well-made, the plastic is sturdy, and there are no assembly defects. I have not used the device in practice yet, as I purchased it recently. The mobile app installed without issues, and synchronization was successful. I bought it for basic self-diagnosis and monitoring of vehicle parameters. I hope the device will prove reliable in further use.
AliExpress Shopper –
Works great! much better than those cheap ones.

“i recently upgraded from a wired scanner to the konnwei kw905 bluetooth obd2 on my 2013 jeep grand cherokee, and it’s been a game-changer. I mostly use it whenever my check engine light comes on, and it quickly gives me clear, real-time diagnostics right on my phone through a fast and stable bluetooth 5.2 connection. The app’s intuitive interface and visual data make understanding engine codes and battery status straightforward, even if you’re not a mechanic. Compared to my old, wired device, this scanner is far more convenient and user-friendly, with smart features like a power button and led indicators that help save battery life. For anyone who wants quick, reliable insights when that dreaded light pops up, this wireless tool is a must-have. A++++ highly recommended.

I highly recommend.

Works impressively well and reads codes correctly. I didn’texpect much for the price. Impressive! Used it on my w202and it worked.
V***i –
The product arrived in a timely manner. The app works well and interfaces quickly with the scanner. It’s good for understanding the car’s anomalies better. It’s also interesting that you can monitor key parameters, such as water temperature, engine speed, etc., from your mobile phone. I used it to better understand the temperature dynamics of the water in the cooling system. I suspected there was a problem with the thermostat and I got confirmation. I will also use it in the future for other machines. Clearly, it is not a tool for modifying control units, etc… but if you are looking for an economical solution to diagnose simple problems, I think the price-performance ratio is worth considering.
AliExpress Shopper –
It’s really, really cheap and the product is useful and I’m using it well.
Use it well in the vehicle and in the app.
J***R –
My order was not working!
The Bluetooth indicator was on but there was no connection to the phone (S24+).
Returns and Refunds
AliExpress Shopper –
The scanner is not responding as described in the manual.
There is no indication of the correct connection when plugged in.
Ignoring this and after several trials it was possible to conect the scanner.
This is not a product for an easy use.
AliExpress Shopper –
Good product! Fast shipping!
AliExpress Shopper –
Love the fact that it works with maxobd & car scanner app. it allows for flexibility & options. however, i will like the developer to include pairing graphs comprehensively in maxobd app as it has more appealing & simplified interface.

Support the use of the pyclip program for diagnosing renault vehicles. This program allows scanning all control modules of the vehicle

a***r –
Excellent quality. Works with iphone.
AliExpress Shopper –
A waste that doesn’t even work with the seller’s app, let alone third-party apps like Carista, for example. Opened a dispute, it was rejected, I definitely DO NOT RECOMMEND it.
