Actually works! Didn’t have much confidence this would’ve any good for the price but it detected the code(s) and with supplied reference guide the condition was confirmed. This also clears the codes from the computer so the (service engine soon light goes out). Of course if not repaired the code will trip the computer again. Recommended to everyone from novice on up as it’s easy to use and takes the guess work out of the annoying service engine soon issues.

Let me know that engine was miss firing and what cylinders. Then it's up to you to figure out why. Also device would not clear codes. However, after fixing the problem the check engine light went out under less that a mile of driving. Overall I am happy with the device and will use in the future as need arises.

Arrived on time and did the things it said it would. Used on my Honda Fit and worked great. I had never used a device to retrieve check engine codes.

I’ve used it twice, on two different cars, and it worked perfectly both times. Comes with a pretty useful owner’s manual and an introductory page of instructions. At $20, can’t beat it.

A diagnostic check at my dealer is about $150. So the device could save you some money or at least keep you informed about proposed repairs. It is easy to operate.

You'll wish you had purchased this OBD2 Kobra code reader a long time ago. It's will the best purchase you've made in a long time (maybe the best purchase ever)!! Do not let the low price fool you! It is worth it's weight in gold!

Does the same as my old one at a 1/9th the cost. Money well spent loop

Love this little scanner. It has saved me more time and money than any device I have used for this purpose so far. Very easy to use and was priced just right. I recommend this scanner to anyone who is working with check engine light P codes.

Easy to use. Easy to read.A link to a storage case or bag would be helpful.

Great for a diy person or at least to get the code and not get ripped off my mechanics trying to sell you other work. I use it just to get the code and figure out whether i can do the work myself or need a pro. Easy to use and pretty actually(compared code to that given by auto zone).
