Customer Ratings & Reviews

This product has paid for itself just after the first use only. I had my check engine light come on and every mechanic near me wanted at least $100 just to read the code. I bought this to see if it would read it for me and it did, I was already saving. It read the code without issue, it was a small EVAP leak, read online about it and got a new gas cap. I erased the code with this scanner and it has not come back at all. So this thing has saved me a bunch already and now will use it in the future to see what code pops up so I know what is wrong before I bring it in for service so I know they are not trying to do work that does not need to be done. I also read the manual and tried out the other functions, the battery voltage works fine, that will come in handy in the winter for sure. Also, I like how it has a code dictionary on it as well, so that way I can at least look it up without having to pull out my cellphone. The screen is easy to read and bright. I also like the Live Data option, it lets you see a ton of stats. Overall I am very happy with this and would for sure recommend it.

I'm not a mechanic by any means, so I was always using an elm327. However that unit required you to have an app to connect to in order to diagnose the car. Most apps were paid for if you wanted all the features as well. Then Rexing came along with this unit, which has it's own built in screen and renders the elm, for my purposes, pointless. Aside from being able to view the check engine light codes (and clearing them), you're able to see realtime live data as well (usually a paid for feature in apps. This unit also supports many other features I've no idea how to use yet, but I like that they're there, IF it came to me NEEDing to utilize them. Screen is ample large and bright enough, as well as the layout is intuitive and simple. If I were to change ONE thing, that would be to make the cable longer. It's got a good length now, but different vehicles put the OBD2 port in different locations, and that extra foot or two of cable would definitely help. Overall a solid product.

Scanner is compact and feels great. Super easy to use, has instructions in case you never used a scanner before. Screen looks great. Would recomend to have in your trunk in case you need it.

The Rexing Universal OBD II Scanner is an affordable scanner for basic diagnostics and check engine lights. You just plug it into the OBD port and it works immediately without needing to install an app or Bluetooth. The interface is easy to navigate, and it quickly reads and clears codes while also showing useful live data and emissions monitor info. This device is great for regular drivers, but I'm sure mechanics would find this very useful. Overall, it’s a reliable and beginner-friendly scanner that does exactly what most people need for the price.

Product came quick. I was looking to add an OBD scanner to my DIY drawer and this is exactly what I was looking for. It is simple to set up and use right out of the box. Screen us large enough to read and it's clear. It helped me instantly check & clear an engine light on my wife's vehicle. Local repair shop wanted $100 just to check the code and clear it. Highly recommend it to anyone looking to check codes to see if it can be cleared or an easy replacement part that can be done at home.

I am Rexing customer from a long time and usually stick to same brand once I trust them. I was looking for OBD scanner as my current one died so found this Rexing product. It was light weight, bid clear screen and does what it's supposed to do. 100% recommend.

I recently picked up the Rexing OBDII-R1 and so far it’s been a solid little scanner. Setup was simple — just plug it into the OBD2 port and it powers on right away. The interface is easy to navigate and it quickly reads codes and vehicle information without any hassle. One thing I really like is the amount of information it gives you beyond just reading engine codes. Features like voltage monitoring, the built-in code library, live data view, vehicle information display, and freeze frame playback make it feel more useful than a basic scanner. I also like that the freeze frame feature lets you go back and look at stored data afterward instead of trying to catch everything in real time. One small issue I noticed is when reading DTCs, the screen says “press any key” to continue, but pressing the OK button keeps it reading instead of moving forward. You have to press a different button for it to continue, which was a little confusing at first.

I've been buying Rexing dash cam products and they are all reliable. Now, they are into the OBD-II scanner field and I'm sure this product will be reliable too! This product is very user-friendly. The display and texts are very legible. I was able to scan and check my battery's voltage when engine is off and when engine is on! It also shows me my car's VIN, O2 sensor readings, etc. Hopefully, I won't be using this device for CEL in the future!

I received the new Rexing Universal OBD II Scanner a week ago and was anxious to try it out on my Toyota Prius V. Refer to your car's owner manual to locate the OBD port. Plug it in, and it's ready to read your diagnostic codes. The user interface is good, though it has a learning curve for locating a specific test. The screen quality is very good and easy to read. I'm not a mechanic, but this helped me locate a problem with my car. Over the past month, the 12-volt battery was draining quickly, and I couldn't figure out what was running after the car was shut off. I took it to my local Toyota dealer, who ran their tests and unplugged several wires from the fuse box. Suspected my dash cam. It ran fine for a couple of days, but was dead in 48 hours again. So I returned to Toyota for more diagnostics. They couldn't find anything else wrong. I would charge up the battery, drive a day, and then it would be dead again. Thankfully, the Rexing OBD arrived, so I tried it. Guess what? The diagnostics reported a weak battery. I returned to Toyota and asked to have the battery replaced. Everything is working great now. Toyota reimbursed me for the previous visits. Thank you, Rexing.

This a nice little tool to keep around for troubleshooting those pesky DTC codes. It plugs right in, powers on instantly, and you can quickly scan and delete codes. There is a pretty simple onscreen menu, and was easy enough to find my way around to check out the different modes. I'll definitely keep this on hand for the next time a code pops up and save myself a trip to Autozone.

I bought this to keep around for older vehicles and basic car troubleshooting, and it does exactly what I needed. If you have an older car or truck with a check engine light, rough idle, hesitation, emissions issue, or just want to know what code is being thrown before guessing at parts, this is a useful tool to have. It is easy to plug in and simple enough to use without needing to be a mechanic. It gives you the code so you can start narrowing down the problem instead of paying someone just to scan it. For people who work on their own cars, or have a higher-mileage vehicle that occasionally acts up, it can save time and money. It is not a high-end shop scanner, so I would not expect it to do everything a professional diagnostic tool can do. But for basic OBD II codes and general troubleshooting, it works well and is worth the price. Good little tool to keep in the garage or glove box.

Great little scanner for the price. Plugged it in, read my check engine code within seconds, and was easy to navigate. Saves you a trip to the auto parts store to understand what’s going on. Good to have.

This Rexing OBD II scanner is a great value for anyone who wants a straightforward and reliable diagnostic tool. It’s truly plug-and-play—no apps, batteries, or complicated setup needed. Just connect it and you can quickly read and clear check engine codes, which can save a trip to the mechanic. The built-in screen is clear and easy to navigate, and the live data and emissions readiness features are a nice bonus for the price. It also works with a wide range of 1996+ vehicles, making it very versatile. Overall, it’s perfect for basic diagnostics and peace of mind. The only minor downside is that it’s limited to engine-related systems, but for most users, it does exactly what you need it to do.

Love Rexing products, the OBD II scanner is very practical. I like the extra features it has. The emissions readiness is really helpful as well. Great scanner to keep in the car with you.

I needed a OBD II scanner for my tool box in the car. So I did not want to spend a lot of money. I found this Rexing scanner and decided to give it a try. I was highly impressed with it, most cheaper scanners don't do a lot or work on all cars. I am happy to say that I have had no problems scanning Mini's gas & electric, Chevrolet gas & electric, Ford, Toyota and Honda so far. You can see & clear codes along with live data. This is a great OBD II scanner!

Need to know why your check engine lights on? Need to clear it? Yep this can do it for you. But wait theres more!!! This has live readings on your vehicle. Say its a O2 sensor, run the vehicle and see real live readings on that sensor! Evap test also. This thing is better then a boring check engine light tool. And for the price!!!!! This price is amazing for what all it does!!!!

The device responses quickly immediately plugging onto Honda Odyssey 2026. The fonts clearly dispalyed on the screen. No unpleasant odor like other industrial device. I used it to confirm the battery voltage after intalling the dash camera in a new car. Everything looks good.

I had a code reader that requires a bluetooth connection and an app on my phone. This one does not!! It's functionality is easy to use. Most shops want $$$ just to pull the codes, this does is for free once purchased. Comes with instructions and an easy to read screen.

I got this because a few months back I had my check engine light on but my car seemed to be working fine. I went to a local auto parts store and they read the code for me. Turns out my gas cap wasn't fully tightened. Simple enough, just remove the code and tightened up my gas cap and went on my way. In anticipation of having another potential issue I decided to get this. It was pretty much a no brainer since it wasn't that expensive but would save me time and headache if something like this happened again. It'll be especially good to know what the issue is before a mechanic to make sure they're being honest if there was a more serious issue.

Pulled codes from the obd slot for my neighbor on his infinity suv. It was easy to use just plug in and turn the car on. It read the codes and provided some nice details, press down to see the next code etc. Its a great cheap obdII reader to have on hand.
