Works as expected! Save me a lot of money at the dealership, knowing what was going on with my BMW! It’s easy to read very well-made and great for the price!

This works great! It feels sturdy and well made. It is easy to set up and use. It clears a code on my car due to an O2 sensor. The display is easy to read. I had no trouble with the connection. It was consistent the whole time I used it. I am happy with my purchase.

Pretty good for the cheap pricing! I did expect better especially having multiple different scanners of the year and just had a really nice advanced scanner my stepmom bought me for around the same price on here so also comparing on that. This scanner is great, wish it had StateOfCharge & better battery test or able to perform alternator/starter/battery test like other cheap scanners are able to do. It does say the battery voltage but that’s it so not really advanced. I give it 6.9 out of 10.

Works exactly as it should. Easy to navigate and priced reasonably

Good price for this product, works great! 👍

I had a check engine light come on my 2021 VW Tiguan.... I am not very mechanical but $20.00 for a scanner would be cheaper than a visit to the dealer.... This OBD2 worked easily and although it comes with minimal instructions I plugged it in and turned on the ignition... Hit the DTC (detect trouble codes) button, and it gave me a quick answer. Manufacturers control U3501 code... googled that code and found out my Battery may be low and the ECM may have had low voltage that turned on the check engine light... I cleared the code, and the check engine light went out, and maybe I will replace my battery if this light appears again... maybe the best $20.00 I have spent in a long time.

Bought this to use in my 2010 dodge charger and it seems to read all codes and have the ability to clear them. Exactly what I was looking for.
