got a used car and couldn't pass inspection due to a bunch of monitors not activated after changing to a new battery... some stores were telling me to change the cat converter which would have cost me hundreds of dollars. i didn't believe them, bought this tool and did the whole driving profile thing for a few days while checking with the OBD tool. sure enough it showed me the car monitors were all finally activated. passed emissions test with no issue. it's a bit light and flimsy but it works.

So this isn't the most advanced OBD reader, but for the price it's great. I bought it because I was going to look at some fixer upper cars I was thinking of buying, and it's great being able to check if the check engine light code is on for the reason the owner claims it is without going to a mechanic. Of course, I still recommend getting a mechanic to look at a car you're serious about buying, but this has helped me rule out several lemons without wasting more time. Also nice to be able to share with my friends when their check engine light come on-- So many check engine light codes can just be the seal of the gas cap failing or failure to tighten the gas cap enough-- why pay a mechanic $60+ to tell you you need to replace a $20 part or just be more careful when you can just have one of these on hand? Booklet contains the universal codes, if you get a manufacturer specific one, you'll need to look it up online, which is very easy with Google.

This little gadget more than paid for itself with one issue! My car had an intermittent electrical issue that caused the "check engine" light to come on. I am NOT "automotively gifted." This little scanner was simple to use and gave me clear codes to read and look up in the included book. I googled my code results to understand them further. When I took the car into the shop, I was able to clearly communicate all this information to the mechanic, which helped him to diagnose and fix the problem on the first shot (of course, he did further testing with the more advanced equipment in the shop). I felt so much more knowledgeable and in control of the whole situation than I ever have when bringing a car to the shop before. I am definitely a satisfied customer and would recommend this little gadget to anyone.

I am grateful to have had this scanner on hand. My car was due for tag renewal and it kept failing emissions due to the "no communication" with the computer. I did this 3 times at different service stations. The emissions station uses OBD2 scanners to pass or fail cars. There has been no "check engine light" on in my car. Sure enough, when I hooked my car up to this personal scanner at home it created a "link error" message. This would discourage a lot of people and make them think it wasn't working properly. However, I knew it had nothing to do with the OBD2 scanner, and everything to do with my car since it wasn't able to communicate with the emissions OBD2 and this personal scanner. I was able to do some research online and tweak a few things at home until it was able to communicate with this personal scanner. It turned out to be as simple as changing out a fuse!! After it was able to communicate with my personal scanner I knew it was fixed and it passed emissions!! This scanner saved me hundreds of dollars from bringing into a shop to be fixed and repaired. I probably would have paid for unnecessary repairs in the process. Very grateful and happy to have this product!!

Works well, simple and clear instructions

I purchased this for my husband as a stocking stuffer. I purchased the red one. We have relatively older vehicles that are just getting to the point of needing a little extra maintenance every so often. This will be an excellent tool in diagnosing some of those little errors that sometimes pop up without the hassle and extra money of having to go to the dealer or a repair shop. I asked a mechanic friend who verified the product for quality. All in all I am very pleased with the product and look forward to my husband being able to use it for our vehicles.

Wish I had bought this sooner! Works great and easy to use on my 2001 and 2002 vehicles. Based on auto parts store scans due to check engine light, I thought I had to do expensive repairs to pass emissions. I simply cleared the codes with this scanner and the codes never came back and car passed emissions. This scanner also identified a legit code on another car so I could replace the part and eliminate the check engine light. Instruction manual explains it all. Identifies codes, clears codes, and shows when car is ready to pass emissions inspection.

My son used it. It gave us the information we needed to tell us it was something he could not fix without more knowledge. When we took it to the shop we knew what to expect. They gave my son the further knowledge to be able to fix it himself . Fortunately I have one of the honest shops available.

Very easy to use, just plug and follow the instructions in the manual. I found that some codes cannot be cleared with this device though. It is still worth getting, if you are like me and would like to see why your check engine light is on before bringing your car to the shop. Sometimes the issue can be resolved by looking up the scanned code online and making a quick fix.

I am a mechanic and I can honestly say this is a great device. The plastic is a little cheap feeling and It will take some getting used too but other then that it’s a good product for the price. A guy I work with bought an obd2 for a 100$ And without a doubt this obd2 is by far a better product. This little device is a great cheap product that gets you in the ball park of what is wrong with the vehicle you’re working on. If you’re car is a newer one it’s probably got issues with emission leaks(that for the most part aren’t bad) but the engine light come on takes away from some thing that could be serious so this is a good device to erase the emission leak code also.
