This OBD II works great and it’s simple to use. Plugged it in gave the code PO420 let me know it’s the lower bank 1 sensor. I erased the code due to it said it could be a misfire so I deleted been driving my car light has not came back on. I high recommend this OBD II scanner.

Pros * Good value for the money * Easy to use * Wide compatibility for all types of vehicles new and used * Can be used for several different functions not just reading your engine light code - check battery voltage, real-time diagnostics, etc Cons * None

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 as it should! Gets the job done!

Product worked perfectly well for me

Works great for checking your battery vs alternator output, plus a host of other diagnostics. Works with most any vehicle with an OBC port (which they all pretty much do).

Super easy to use and got the info I needed from my car in seconds. My check engine light turned on for my 2019 Rogue. Connected this under the steering wheel, turned the car on and had my codes immediately. It has the option to reset the codes if you wish to do so. I was able to research the codes on my own, prepare myself for potential financial pain of repairing and was given the same results from the dealership (fortunately was still covered under warranty, so my wallet was spared). For the price and quality, I'd recommend having this. Especially for those with cars a few years old or more - things are bound to happen and even though this won't fix it, you can get an instant read on what's wrong and you can then do your own research on it to see what you may be in for as far as repairs/costs/etc.
