  • Great Diagnostic Tool
Very useful OBD2 scanner. Easy to use and reads codes quickly with clear live data. Helps diagnose issues fast and accurately. Build quality feels solid, and it works well on multiple vehicles. Great value for the price. Highly recommend for DIY and professionals!

  • Solid OBD2 Scanner for Basic Diagnostics
I bought this because I wanted a straightforward OBD2 scanner that could read codes, clear codes, and show live data without needing a subscription or some overly complicated app setup. The FOXWELL NT301 does exactly what I needed. It is easy to use, the screen is readable, and it gives enough information to help diagnose check engine lights and basic drivability issues. The live data feature is especially useful because sometimes a code by itself does not tell the whole story. Being able to look at what the sensors are actually doing makes troubleshooting a lot easier. It is not a full professional shop scan tool, but it is not trying to be. For home mechanics, truck owners, DIY repairs, and general vehicle maintenance, it is a very useful tool to keep around. Simple, practical, and worth having in the garage or vehicle. It can save a lot of guessing, and guessing is usually how parts stores sell unnecessary sensors. ... show more

  • Functional - wish it had more features
The Foxwell NT301 OBD2 scanner works exactly as intended. It plugged in easily, powered right up, and had no problem reading and clearing basic trouble codes. For straightforward diagnostics, it does what it’s supposed to do without any drama. That said, I’ll admit I was a little underwhelmed by the overall feature set. I think my expectations were probably a bit higher than what this model is really designed for. It covers the fundamentals very well — reading codes, clearing them, and showing some live data — but it’s not a deep-dive, advanced diagnostic tool. In the end, I decided to keep it because it handles the basics reliably, and that’s ultimately what I need most of the time. I wouldn’t recommend against it at all. I’d just suggest that anyone considering it take a close look at the listed features to make sure it matches what you’re expecting. In my case, the slight disappointment was likely more about my assumptions than the product itself. ... show more

  • Does everything an at home mechanic needs and more
I was skeptical at first cause it was so cheap but this thing far exceeded my expectations. I could figure what was up with my Jeep but the live readings you get while driving is a game changer(as long as you know how to read the info, otherwise there is guaranteed a YouTube video or forum on the Internet with your answer). You can have all your sensors, cat info, ect in live read out in numbers or even if you need to see it in a graph while the car is running. You can even pick a couple specific things you need to compare while the motor is on and driving or revving simultaneously side by side on the graph to diagnose something. This ain't no$1000 scanner and you can't modify or tune nothing obviously on it but it dang sure ain't just a simple thing to check to see only what codes your trucks check engine light is throwing and to just clear them out either. It's the perfect in-between scanner that'll get you by with enough read outs to more or less figure your issue. Id for sure recommend this to anyone from mechanic to teenager learning about ratios and sensors and how the numbers are supposed to read. Go get this thing and get your hands greasy y'all ... show more

  • Great tester, lots of options great price, and upgradable.
My son has the same unit that I purchased, and I’ve borrowed his so often that I ordered one for myself. But before I did, I watched a YouTube channel called Project Farm. If you’re not familiar with him, he buys different items and compares them. He doesn’t take advertisements or free items; he pays for everything he tests and purchases them from retail sites just like you and me. According to his tests, the Foxwell NT301 has more options and capabilities than all the others he tested, and at a better price. The Foxwell NT301 works on all vehicles and can be updated every year for the latest model, so it will work on any car you have now and in the future. The screen is large, color, and easy to see; you can clear codes, read codes, check oxygen sensors, and see live tests as you drive. It’s an all-around great unit at a fantastic price that saves you from paying big money at your local dealership. ... show more
