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).

Very easy to read the codes you can look up codes it shows you live data quickly diagnose your car in seconds
