Very good obd 2 scanner with a simple code reader and the fact that has a battery test reading is a plus. I definitely recommend this device.

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!

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.

Great tool to have in your tool box. I purchased this scanner because my engine light in my 2017 Chevy Colorado came on. I literally got the scanner the next morning. Plugged it in to the port and it told me my O2 sensor on bank 1 was the problem. It worked fast and it was super easy to use. Not to mention the price that was great to. Thanks you guys for making it more affordable for the DIY guy that I am. I recommend this to everyone.

Does what it's supposed to. Easy to use

Very nice item works perfect 👌

Following the directions to view the error codes always results in a reading of P0000. But using the obvious button on the button panel shows the error code. So it works for that, but still...Haven't dug much into the other functions yet. I probably paid too much for it since plain code readers cost less.
