So much value packed into this tool. The design is clean, it’s compact, and the screen reads crystal clear. Very functional and easy to navigate. It took me under five minutes to figure out how to read and clear codes. I was able to diagnose and clear two EVAP codes with it. Pull the code, look it up, and follow the fault tree. I also really like the EVAP test function and the live data readout in real time. Without that, you’d have to wait for the engine to eventually throw a code, which can take several minutes depending on what the purge valve is doing. Great diagnostic tool for the price.

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.

Code reader was easy to use but the instructions were on the weak side. I bought this to reset a light caused by my battery being bad. Would not read the code or reset. I think there is a plus model or the 501 does it. I should have read more. Oh well.

Works like a champ! I've used it for years on my 2016 Ford F-350 with a 6.7l Powerstroke. It's reliable and easy to use. Works so well i ordered a second one for my other pickup. It's easier to just read and clear a code that pops up rather than drive home with a check engine light. I keep one in each truck. And, it's worked multiple times in -40 degree temperatures. Great product!

Excellent product. Very detailed and very easy to use. The scan tool offers more than most scanners in this price range. Being able to not only scan for codes but having this tool tell you this likely cause of that code is pretty awesome. Zero complaints. Fast, easy and great price.

Hailing from the shade tree mechanic era of points & plugs ignition and the carburetor accelerator pump, most of what goes on that fills the NT301 data stream is way above my pay grade. While the likes of EGR, O2 and catalyst are not beyond my understanding, the value 12.226 associated with a VPWR(V) certainly is. Being the consummate motor head, the dreaded "service engine soon" lit up for the first time from behind its mask on my dashboard finally gave me the impetus to purchase a code reader. Upon some goodly research, and a screaming hot Amazon deal (a few bucks more than the NT201), I settled on the NT301 and I'm not disappointed. I had two reasons for the purchase: 1) To read the code(s) and have some knowledge in advance of a mandatory visit to a repair shop as that "service engine soon" (or "check engine") light is grounds for instant rejection for my county's annual inspection, even if the good ol' tailpipe sniffing and other "hands on" checks would pass the Federal mandates. As well, it might reveal a serious issue that shouldn't be ignored. 2) To satisfy that ubiquitous question: how can one turn that light off if one wanted to? Searching teh googuhl for either "check engine" or "service engine soon" returns gazillions of hits with bazillions for ODB scanners. Makers, sellers, yoot oobs, reviews, best of... oh my. Not to mention, "over 1000 results" here on the 'zon. I opened NT301_OBDII_V1.00.pdf (the equivalent of the printed manual) in Tracker Software's PDF-XChange Viewer and used its powerful search engine to help out. The words "check engine" or "service engine soon" do not appear in the manual. Instead, one finds section 4.2, Erase codes, for the two choices - an "Erase hot key" and an Erase Codes item in the diagnostic menu. The reference to the hot key appears no where else. The down key has a big old ERASE printed on it. Section 2.1 refers to that as a "Quick access to the Clear Codes function before going to diagnostic menu..." And that's it. Clear = Erase?? Hot key = Quick access?? Fortunately, using the down/ERASE key (you really, really need down) didn't seem to erase or clear anything. My "service engine soon" light remained shining bright as my county and the Federal bureaucrats and repair shops far and wide would have it. I'm OK with that, but in that respect, an obscure "Erase hot key" is dangerous if that shuts off the light. Yet, the question remains, does NT301 anything extinguish the light? Another documentation shortcoming is illustrated in figure 4-30. Although the green check mark and the no symbol can be presumed, my result had two white-X-on-red results with no explanation on what that means. Considering the Federal legal implications of the environmental technology presented by the the I/M Readiness Status, the documentation focuses only on the the three simple LEDs while fully ignoring the really neat Diagnostic Menu Screen. All that said, even at the regular price, the NT301 seems to deliver a great bang for the buck. Further, I'm motivated to hit the books, uh, internet and study up on some of this OBD stuff. Kudos for the 08/01/18 firmware (v4.24) burn date on an 08/15 purchase. A pleasant surprise. But I've got to ding two stars for omitting The Obvious from the manual. Some other reviewers here are less than satisfied with the manual as well. Admittedly, the manual should not be held to the standard of a concise tutorial. SIDEBAR: The problem was repaired; the car passed emissions testing. I still have the two white-X-on-red symbols in the I/M Readiness Status Diagnostic Menu Screen. So, what the heck...
