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

Very nice inexpensive OBD reader. I keep it in the car for any lights that show up. Simple and effective.

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.

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).

I got this because my check engine light came on suddenly a few weeks ago. I wanted to first see if the issue was caused by something I could resolve before handing over large sums of money to a mechanic. This product was reasonably priced, so I decided to just roll the dice and give it a try. My car was due for yearly inspection, and it will not 'pass' if any diagnostic codes are found. First, this product is VERY easy to use. It took a minute or 2 to figure out how the buttons work for navigation, but not too long. I didn't need any instruction manual or anything. I plugged it in to the diagnostic port and the scanner quickly found 1 code: P0422 "Evaporative System Emission leak (small leak)". I had NO idea what that was and simply googled it. The most common cause listed was something wrong with your Gas Cap: Either loose or defective. According to all the stuff on Google, it COULD be something more serious, but these were the most likely causes. I was immediately RELIEVED that the cause was most likely not 'serious'. I made sure the Gas Cap was tight. That didn't work. I cleaned the Gas Cap with WD-40 and tried again. That didn't work. Check engine light stayed on for a couple more days. Finally, I inspected the gas cap with a light and magnifier and saw 'cracks' and stuff from time/age. So, I found and bought a replacement Gas Cap off Amazon for about $8 bucks and replaced my gas cap. A couple days later, I noticed the checked engine light had turned off and I haven't seen it since. This was DEFINITELY worth the money to see if it was an issue I could resolve myself before spending money and TIME at the mechanic. It gave me a QUICK and accurate reading that let me fix the issue.

Product (when I finally got it) worked as expected. Lost 2 stars because at first I was shipped 2 junk parts in an opened package with a grease stained user manual. It was made right, but I still had to spend gas and time to make the return; I ordered rather than buying in store to avoid the trip.
