I don’t know how but this scanner does the job right, I think it’s UI and data it presents are very good and well thought out. Sure, the numbers are confusing but it’s just a quick google search. I think it connects well between phone and car. Pretty good and I needed it to diagnose something, did just the thing I needed it to and now it’s used to track numbers. Great for its price!

The device connects to the phone quickly and the Android app UI is intuitive and easy to use. I also like that you can pull info on the codes right from the app. I don't have any codes right now, so I didn't fully test this functionality but on paper it sounds great.I purchased the package with the Ancel BST100 Battery Load tester which also works great,. This is an excellent value and I highly recommend it.

It does everything it’s supposed to, and well enough that I’ll keep it. However the app for it is kinda garbage tbh.Oh well, it works and was relatively inexpensive. So it’s still passing marks from me.

As a wholesaler just looking for a an inexpensive scanner this has been a great tool. IT is great that you can just read the codes from the tool itself you don't need the app but there is an app if that is what you prefer to use. It doesn't read air bag lights but that was known before hand. I have yet to find a car it does not hook up to.

Works great.; easy to use. I didn't setup Bluetooth. Just press the button on the left side and your good. I carry in my vehicle. It'll tell you if the vehicle is carrying a permanent code. Clearing code doesn't remove it permanently for some code. Why? IDK, ask your mechanic.

2011 Silverado 1500It’s ok, monitors basic functions, clears codes etc. check you can use all the features with your make/model/year etc, mine won’t even run the basic battery test

For the average quasi-car guy this is the sweet spot. I tried a highly rated $14 dongle and downloaded and tried 3 different Android apps. I discovered that one app was incompatible (description never implied this), two connected right away. But I had questions about intended functionality that I sent in to both the dongle and app people. After repeated queries and 4 days nary a peep. They seemed to work ok but always a question of what they were and were not intended to do. And one app was particularly unpredictable when trying to configure new gauges.Then I came across this integrated system. What attracted me to it was the interface that can remain semi-permanantly attached to the dash with the compatibilty with the app designed for this device. No guessing about compatibility. They are designed to work together. And I don't have to use my phone all the time - only when I want a larger screen or to take a deeper dive into the readings.The system turns off after a few minutes of ignition off and turns on when the button on the left side is pushed. It is always available and informative.Sure, it is not the full-featured $$$ system used in shops- probably 10% of the cost of what's in the shop. But I'm guessing it does 90% of what most of us need to know.So for casual users who have an older vehicle (mine is a 2017 Mazda) who don't want surprises or much guessing about the performance of their vehicle, I consider this the sweet spot among similar devices.
