For anyone who wants a straightforward OBD2 tool without spending a fortune, this one gets the job done.”

Customer Review: “Does the job pretty well. You can see live data and diagnose your car for any major issue without even going to the mechanic which would cost you $75-125 for doing the same thing. Very easy to install and operate. I had to use once and it read the codes accurately.”

Plugged it into the OBD2 port and it powered on instantly, no batteries or setup headaches. The menu is pretty straightforward and easy to navigate, even if you’re not super technical.It reads and clears codes fast, and I like that it shows descriptions instead of just numbers, which saves time googling everything. Screen is clear and bright enough to read even in daylight. Build quality feels solid and the cable is thick and durable.For basic diagnostics and maintenance checks this thing is honestly perfect. Already saved me a trip to the mechanic. Great value for the price.”

Customer Review: “I really liked this VECOONEEN OBD2 scanner. It’s very practical and easy to use. I tested it on my Prius, and it quickly showed that the issue was a failing oxygen sensor.The scanner provided accurate information and saved me time by helping identify the problem right away. A great tool to have for basic diagnostics.”

Customer Review: “UPDATE: the unit won’t work if you don’t do updates. It works fine once you do updates.I am getting various transmission codes. I’ve researched the forums and YouTube. This allowed me to look at the specific codes (P0843, P0877, P0751, etc) and the components. I was able to look at all my shift solenoids, Pressure switch’s, and trans temperature at the same time. It was 15F outside and I was able to see the trans temperature read 80F, and if I cleared the code and shifted it went to limp mode, and then the transmission read -40F. I’m replacing the Pressure Switch assembly (ALLISON TRANSMISSION 29546972 PRESSURE SWITCH ASSEMBLY 5-SPEED & 6-SPEED 01-18) and expect the temperature to read correctly. The gauge reads correctly today after clearing the code.I bought this for my Chevy 2500 with a Duramax engine to read a code. Basic code readers were giving me a generic code (P0700) and this was snow to give me more specific detail (shift solenoid 2) as well as the ability to move monitor data. Similar to my CTS Edge scanner it can show balance rates, and SOOOO much more. It was worth the $150 for figuring out my error code so I could research potential solutions (low fluid, frayed wires, bad harness) instead of constantly having a no shift problem. Some say the software stops working in a few months, but after two days of playing with it I’m happy for the one time.It automatically detects your vin. Also, it stores stuff on servers in China (if you couldn’t tell by the price) so if you want USA made this isn’t it. If you shop at Walmart, Target, or Auto Zone you’ll be right at home.This is not a programmer. It won’t turn off features you don’t like. It could help diagnose a misfire, monitor transmission or engine coolant temps, tell you the flow plug status, etc.”

Customer Review: “Great product worth every penny app is a bit pricey if your not going to use it often but a must have tool for car repair tells you codes and exact issues also tells you step by step how to fix it. As well as an AI mechanic to asked question and call support as well it helps you know a price range for shops so you don’t get over charged for repairs. I used it yesterday when looking at a car which had no codes on the dash FIXD told me the pending codes and also made me aware the codes were recently cleared which gave me such piece of mind. Knowing a serious community de was cleared prior to me looking at the vehicle. I’ve decided to pay for the year subscription”

Customer Review: “This little item works great, but it has a small caveat if you want its full functionality.As OBDII scanners go, this one does the job at a fraction of the price of a professional scanner. It shows all the information on the screen in an easy to set up software with an intuitive menu. Easy for even the least mechanically inclined people to use. However, you’ll need a separate iPhone, iPad, or Android device to install the app onto.It color codes the issues as to their importance. Green means you should be fine and it’s more of a suggestion than an issue, Yellow means check it out soon or have a mechanic take a look, Red means you should probably stop driving your car and set it on fire. Just kidding. But the information is displayed fully with the OBDII codes along with the explanations as to what they are. In my case, there was a Stored Code and a few Pending Codes. The Stored Code defined what the code is, however the Pending Codes showed ‘Unknown Issue’. I had to go online later to look them up. There’s also an option to clear the dash lights that did not work for me. So does the scanner work? Definitely. Is it worth it? Probably not, and here’s why.The caveat I mentioned? You have to purchase their Premium version at a yearly fee of $99.00 if you want to unlock the scanner’s full potential. It includes;”Cost and repair estimates from the Identifix database, Unlimited calls to our FIXD Mechanic Hotline for a trusted second opinion and DIY help from our network of ASE certified mechanics, And much more! FIXD Premium is a monthly subscription that is optional and is not required for use of the sensor.”After the purchase price of $37, that makes this little bugger $137 right off the bat, with an additional $99/year after that. However, they do let you try it free for one week (cancel at any time). If you’re using this scanner for multiple vehicles, and you’re getting paid for it, then you might find the fee not so much of an inconvenience. However, if you’re like me and are only using it on your daily driver, how often do you think you’re going to use it to qualify that fee? I used it this once, found the codes, and now it’ll probably sit on a shelf until the next time the need arises for it. And since I’m mechanically inclined, I can resolve the issues on my own. But, again, “the subscription is optional and is not required for use of the sensor.”If you want a scanner that offers more functionality with no extra costs involved then purchase one of those instead. But if you’re an average Joe or Jolene and you just want to see why your car has those dash lights always on, then this little guy does the job just fine.”

Customer Review: “Works great with my iPhone 16Pro running iOS 26.3 and 26.2.1. Just used this morning with Carista app on iPhone customizing my 4Runner settings. Haven’t tried on iPad yet.One app took a long time to connect but finally did “car scanner elm obd2”. Not sure why though. But it works great after it connects and lots of customization abilities in free version, surprising! But great.”

Customer Review: “My second unit. I had one for my JKU. Now have a Gladiator. Works great. Way cheaper and easier to operate than the tazer ones.”
