KONNWEI KW850 Professional OBD2 Scanner Auto Code Reader Diagnostic Check Engine Light Scan Tool for OBD II Cars After 1996(Original)

Awesome scan tool that anyone can use to check and clear the dreaded check engine light. I've owned the more advanced much more expensive scan tools and this one def gives you more bang for your buck!!! It does everything one 3x's the cost does with complete ease. Large screen that is very easy to read, easy to follow directions, a complete library of codes, a search option, will provide graphs if desired, has a print featureand real time data you can track while driving! I couldn't be happier!!! I'm gonna be sending some out as gifts!!

I searched many similar products and decided to buy this one for its features/price/good review. This tool is a must have for old car owners. It is easy to use and provides more useful functions and features than the OBD2 Scanner I had before. It is a handy tool when your car's check engine light turns on. It will save you time and money. One feature I like the most is the I/M Readiness, which will tell you if your car is ready for Smog Check. I also like the Battery Test function and the extra-long cable. I tested it on my Camry and Odyssey. It worked great!

My husband was so excited when this showed up! We have a Passau with a gas engine, and it has been acting up a lot lately - moreso it seems on his way to work, so he has been doing some easy fixes on his lunch breaks. That being said he has to know what is wrong, so we got this to he in his car so he can read codes. The great thing is this one displays both the code and what the code means. It also is quick and easy to use. He does wish it had a battery operated option, but that's not a big deal in the end. It seems to be good quality. It read accurately on our latest issue, was quick, the rubber and plastic seem to be nice quality. Also, the screen is very clear. My husband's favorite feature is the nice carrying case. The details matter. :)

I liked the feel of it, its big, good grip.Options are reasonable for what you pay, the programming seems solid.My only hang-up is the housing, okay, but seems like sorta cheap plastic with a removable rubber outliner. Not Waterproof, so be careful around wet areas.The PC software might need a bit of polishing, but okay I guess, considering you'll only use it for updates, data viewing and printouts.Now what I did with it first think I got it:First, I updated the first one (Black KW850), everything went well.Then I went on to update the second one (Red KW850), now this one it didn't pick up, so I contacted customer service through email. They responded rather quickly and they helped extensively.Red KW850 came out of box with firmware Ver: 4.1, could not connect to software to search updates. It recognized, just didn't give the option for a search or at least a display "latest firmware installed", something.Black KW850 came out of box with firmware Ver: 2.1, the software updated it to Ver: 3.2, took 5 minutes done.Now I've tried to get it connect, it sees it, but the update button doesn't highlight to do a search.Now I've asked the rep about it and if I should be concerned about it.They told me I really shouldn't, the programming is pretty set and usually the updates are pretty small and few/far in-between. Most of the time the updates are mostly language related, like if they add a language for foreign use. But other than that it works Fairley well, at least just for personal use and maybe quick/easy professional use.So bottom line:good product, solid OBD2 programming, decent enough PC software (bit of work needed), housing okay (could be better w/added Waterproofing), solid OBD2 cable, comes with storage bag (thats a plus), pretty good manual (clear cut instructions & explanations). All in all, im good with it, for the price.Just so whoever reads this, Version's:Konnwei OBD2 KW850KW850 ProfessionalKW860KW870 w/ direct battery adapter cable (Unavailable on Amazon)

I highly recommend this OBD2 scanner. It is easy to use, works flawlessly & will save you money over the lifetime of your vehicle. I have never used this type of scanner/diagnostic tool, I have the type where you can read/erase vehicle engine codes. I can tell you this thing does so much more, everything from reading, to giving information on the cause of your CEL, to erasing those codes. I love the monitoring ability of this tool and the instant access to what's going on with my vehicle. And what's even better is I can record it and download it later.Outstanding tool!!

I purchased the KONNWEI 850. It is a very sufficient and easy diagnostic tool that even a novice home mechanic can use. The instruction manual that comes with the ODBII scanner is straight forward and easy to understand. I was able to diagnose an issue that my car was having within minutes. It saved me from ordering unnecessary parts and helped me repair my car easily without having to take it to a dealer. I recommend this tool to any DIY mechanic or even professional ASE certified mechanics. The price is very reasonable considering what you can achieve with the use of this device.
