Works great. My 2010 Silverado tripped a code on the engine. This little device told me I had an air leak, likely from my gas cap. Sure enough, I replaced the gas cap, reset the error code and that took care of it. At this price, every backyard mechanic, or anyone with a car should have one or know who has one. At this price point, it's a great bargain. One last thing, it does not just give you a code like some do, it tells you what the code means in English. Nice!

This scanner does exactly what I expect it to do. I'm able to read codes on my 2005 GMC to see exactly what is throwing the alert on my pickup and then fix it. There are nicer ones available with better displays and all that, but I like simple and I get all the functionality I need from this thing for a really cheap price. I'd recommend this to anyone needing to fill those roles.

I think this product was defective in that it did not read, "C.A N. OBD 2" in the display as it says in the User Manual step 3. It read Kobra. The E Tech with Kobra Products responded quickly and provided a quick guide instructions which I tried. The device then went through the protocols and went into, " Link Error " mode. I tried it on two vehicles and got the same results. I appreciate the E Techs prompt responses and willingness to offer and give me a full refund as I was not able to get the device to operate properly. Thanks again KOBRA Products E Tech.

Great simple device. Item arrived with instruction manual (which included a listing of codes and descriptions) in a resealable ziplock-like plastic bag. It did have the look of having been used before. That didn't matter because it was in good shape and worked exactly as promised. Follow the very simple directions and you should have your diagnostics in minutes. After getting the code and description from the device (and manual) I simply googled my car make/model/year with the code. this further described the potential issue, symptoms I may be seeing and possible corrective actions. My code told me that there was an issue with the MAF (?). I am not a car guy and this meant nothing to me. But after googling I understood the potential issue. Before taking it to the repair place I did the simple DIY suggestions found the internet and corrected the problem by simply changing the air filter. Spent $18-ish on this device and another $10 for an air filter and my problem was fixed. Taking it in for car repair would have cost an extra $100 minimum.
