Worth it!!!

Really love this little OBDII scanner. Quick determines the vehicle make and is able to pull and clear codes. The live data stream function, however, is the real star here, allowing you to diagnose issues with the emissions system. While it doesn't do live graphing like some of the higher priced models, you can still do some reasonable investigatory work in pinpointing problems with your system, such as oxygen sensor voltages and fuel trims.
While some of the bluetooth OBDII products are also quite strong (especially when used with an app), I have found that they don't handshake with as wide a range of vehicles as this little guy does. So this makes a great backup or just something to leave in the glove compartment in case of emergencies.

Great purchase!

Having a tough time smogging an old Camry with a converter test incomplete. This tool let me pinpoint what tests passed and which one I needed to complete for California smog test. Still can't get the car to pass the test, but the tool diagnosed my problem accurately. I had no prior experience with any kind of diagnosis tool. This was easy to use. Worth the money for sure

Great purchase!

I ride a Yamaha motorcycle that is fully electronic. Had a fault light illuminate on the dash. The bike would not start without clearing the fault.
Easy hookup to the universal data port.
The reader is very easy to use and it quickly dentified the fault and gave me options. Knowing the fault was a random nuisance caused by the bikes traction control, I erased the fault. The motorcycle started right up when I turned the key on.
The reader is small enough to carry under my seat. I rest confident if this issue appears again I can fix it anywhere in my travels. I won't be stuck someplace for any nuisance fault.
The instructions are minimal, hooking up to the data port turned the reader on. Follow the prompts from the reader. It's simple.

Good Product

I have used this code reader several times since I purchased it. I was having an issue with my Subaru Forester with warning lights coming on. After clearing the codes a few times to make sure it was a false positive, I replaced the lower O2 Sensor. This code reader told me exactly which sensor was bad and have not had any issues after the O2 Sensor was replaced. Not having to worry about replacing batteries is also a nice feature since it's powered by the OBD2 connector.

Good Product

The scanner was very easy to use & accurate. I was able to diagnose my 2010 Ford Expedition's check engine light issue pretty easily. Since it was an oxygen sensor notorious for being difficult to get out, I was unable to fix the problem myself. However, I was able to call the auto shop, tell them the error code (P0130) & symptoms. The shop was able to order the part I needed BEFORE I took my vehicle in & I was able to get done in about 2 hours versus a couple days. WORTH IT.
