The product is good. Works as expected.

Injectors firing mentianNot showing

I am so so very happy with the OBD2 Scanner as I was able to clear a error code that has been dogging me for the longest time and turned out to be the catalytic convertor which needed to be cleaned with a special solution from the dealer !!! So glad I invested in the unit ... Also helpful in clearing codes in my daughters Mazda's !! 100% extremely satisfied with the unit. Extremely easy to use an work with !!!!!

Not useful

I have always used the Bluetooth modules to read codes of the OBDII port. Always vanished from sight for some strange reason. I tend to not put things back in a rememberable spot, so it is my wrongdoing.Anyway, I decided to go with a fully self-contained reader and this thing is much easier to use than the others.By others I mean the Bluetooth, wi-fi whaa?, it won't connect, maybe turn it off then on again, wait it has no power switch, maybe it's my phone, lose me I dare you, maybe it is IOS, or maybe it just is a dud, why did I buy you thingy, I hate you thingy, I will lose you forever!Enter this little gem. Powered by the OBDII port of your car so no batteries needed. No silly app to download with optional purchases for your vehicle, and no I didn't give them my email address either. Just plugged it in and in 15 seconds, the device was awaiting my input. ready to work out of the box.The screen was easy to read with my 54 year old eyeballs, no squinting needed! Self explanatory menu, easy to understand. My Mustang has a faulty fuel injector , I just googled the Pcode. This is no pro model at this price point. It does not diagnose and troubleshoot the vehicle. It will read the codes stored in the car's computer that mostly relate to emissions. Engine misfires, cats not up to temp, O2 sensors, fuel injectors misfiring, engine running lean or rich, etc. It will tell you what code is causing the check engine light to come on. It will also clear it. A word of caution, do not reset codes before you have to take the car to emissions. Most cars need to 'cycle' through several real world tests to show a status of READY, which is what the emissions testing looks for. It took me a week of highway driving, street driving, heat up and cool down cycles, shifting through all the gears then slowing down by coasting with no brakes. Every car is different, so just google "OBD readiness Drive cycle" and the make and model and year of the car.Note:If possible, when working on a vehicle either before or after an E-Check OBD II test; do not clear theDiagnostic Trouble Codes (DTC’s) so that the check engine light remains on after the repair(s).Therefore, if it was the correct repair, the check engine light will turn off on its own while driving thevehicle through its drive cycle and signals to the driver that the vehicle is ready to be tested. If the checkengine light does not turn off, then additional repair(s) may be required. Remind your repair technicianIf the repairs require the computer codes to be cleared or a battery disconnect (which also clears them),then be sure to drive the vehicle for at least two or three days (older vehicles may take more time)including both highway and city miles. This will result in setting the OBD monitors to “ready” and readyfor an emissions test. Unfortunately, when the codes are cleared it turns the check engine light off and itis a guessing game as to when the computer monitors are “ready.” The generic drive cycle below mayor may not be helpful but it will give you a better idea of what driving parameters usually need to bemet. This may need to be repeated 2 to 5 times depending on the make, model and age of the vehicle.*Do this all at the same time and not in pieces (does not need to be exact)1. Let the vehicle sit for 8 hours2. Start the vehicle and let it warm up3. Drive for at least 10 minutes at highway speeds (55 mph or more)4. Drive for at least 20 minutes in urban traffic with at least 4 idle periodsthat you prefer to keep the check engine light on after the repair(s) if possible.I had to learn all that the hard way btw.All in all, I recommend this product for purchase as a good buy, and great value for the money.Ray

Works well and easy to use.

Simple set up and operation. Better than some more expensive units
