Four StarsReview by David S. [Amazon Review]
Gives me a peace of mind knowing I can trouble shoot my vehicle. (Posted on 11/16/2016)
Works great with FORScan software on Powerstroke 7.3 Diesels! Injector Buzz Test, CCT, all sensors, etc.Review by Lava Lamps [Amazon Review]
I bought it to use with 'FORScan' software on a 2000 Ford 7.3 Powerstroke diesel... after downloading drivers for Win 8/10, the combo works great!

This adapter has the proper chip & interface implementation with higher speed capabilities for performing real-time diagnostic functions.

FORScan is a software scanner for Ford, Mazda, Lincoln and Mercury vehicles, and a free download for Windows. It can do the 'Injector Buzz' and CCT (cylinder contribution) tests, which are specific to the 7.3 and 6.0 PCM. Furthermore, it will also monitor and display PerDel (Percent Deceleration of crankshaft) for each cylinder, which is extremely helpful for diagnosing a variety of issues with Ford Powerstroke engines.

The software can monitor all sensors in real-time. e.g. ICP, IPR, EOT, ECT, voltages, etc. It has logging, graphing (O-scope) and other features.

Windows 7/8/10 (plus Linux, Android OSX, iOS) drivers for this adapter:

Perfect for DIYReview by J2daEWW [Amazon Review]
Very happy. Cord is good quality and the software is good enough for the DIY. Looking for higher quality software that doesn't cost an arm and a leg is a little hard, but this is a perfect start!

I am using an old 10 inch HP laptop with a small Intel mobile processor and works great. (Posted on 11/16/2016)
Worth itReview by T. Jefferson [Amazon Review]
Worth the extra money over the $5 ELM327 adapters. I went through several before finding that this one works well with Torque on my Pumpkin in dash Android Stereo. It's significantly faster than the Bluetooth connection i was using and I no longer have to suffer through re-pairing. (Posted on 11/16/2016)
I like the ability to know why the "check engine" light ...Review by Glenn Dawn [Amazon Review]
It works exactly as advertised and was delivered a day earlier than forecast. I have a Windows 10 HP laptop and it connected to the car with no problems. I like the ability to know why the "check engine" light comes on and the ability to reset it. I use it te connect to our 2008 Chrysler Town & Country van. (Posted on 11/16/2016)
Worked Where Bluetooth FailedReview by Dazedgonebye [Amazon Review]
Works as advertised and the software that comes along with it is easy enough to use.
That said, I wish the software had a feature to allow you to mark events as they occur.
I have an older car and the cheap bluetooth OBDII dongles were not able to communicate with my car's ECU. USB and a laptop may seem a clunky solution, but it works and it's cheap.
I would buy again. (Posted on 8/16/2016)
Highly recommendReview by willy [Amazon Review]
This is the best value for the $$$. Just download the for free software and enter the activation key that comes with the device and with that you have full access to all your vehicles codes and it is very easy to reset trouble codes. Another big plus is there is free online access to almost all the codes which could potentially save big $$$ whether you do the repairs or you bring it to a shop. (Posted on 8/16/2016)
Easy to use inexpensive scan toolReview by Joey Rodriguez [Amazon Review]
It met my expectations, I was able to use it with my Android phone and laptop pc. I used to use a Snap-on diagnostic scan tool years ago. I hope to upgrade the software in the future so I can utilize the full diagnostic capabilities to maintain my '03 Chevy Silverado 1500, as I plan on keeping the truck for many years. I am a retired heavy equipment mechanic that used to repair car's and pickups on the side. (Posted on 8/16/2016)
Works great on my 2015 MazdaReview by Doc161 [Amazon Review]
Works great on my 2015 Mazda! I have this plugged into my car-puter and love having extra gouges on the dash - screen. I have also used this to read and reset a few check engine lights on my car and some for friends. Sure beats paying a $80 diagnostic fee at a shop! (Posted on 8/16/2016)
MacBook Pro (Mid 2012) Windows 10Review by Amazon Customer [Amazon Review]
The thing works great so far. I use it in combination with a MacBook Pro (Mid 2012) running Windows 10. I had no issues installing or running the OBDWiz software that was included. So far I've tested the device with my 2008 Acura TSX, and my 99 Nissan Altima. The software does provide some data for one car and not the other, and vice versa, but does an adequate job of displaying the most relevant data for both cars (Fuel economy, MAF readings, O2 Sensor readings, etc.). Hope someone finds this review helpful. (Posted on 8/16/2016)
Inexpensive alternative to hand-held scanner. More bang for your buck than a $100+ hand held scanner.Review by Amazon Customer [Amazon Review]
Have a 2004 Lincoln Navigator. I kept getting the SES light. Using the hand-held code scanner I would get P0453 and looked it up on the internet. Never really found what I was looking for. Finally, I ordered this, installed the software on my laptop and saw what it said about the code. Not only did it tell me what was wrong, it also said that accompanying this problem would be the smell of gasoline fumes. That is exactly what was going on! I replaced the bad Fuel Tank Pressure sensor connected to the fuel fill return hose and used the software to clear the code. No more fuel smell and no more SES code. I have been using hand-held scanners for years and I know now that I have been doing it wrong. (Posted on 8/16/2016)
An Inexpensive OBD II scanner that Kix Azz over the Name Brands for the Price.Review by INONUTN [Amazon Review]
Wow! Totally Surprised!
I can write a whole long story , but i'll keep it Short. I'm a pretty Good Home Mechanic, Rebuilding Engines to Transmissions from the ground up. I have to say, this Product did more for teh price then my Well Known named brand product did. My daughter had her CEL come on, I have 2 different branded Scan Tools & None could even read the Vehicle (Not sure Why) brought to the shops and 3 others shop with different scan tools Still Error. So i took a chance and ordered 2 OBD II scan tools on Amazon, 1 was this & another was the BAFX. By surprise Both was able to communicated with the Vehicle. But only this product with its PC software was able to pull the Code. To my surprise it was a Transmission Code, and not the Engine Code. Out of curiosity i borrowed a friends OBD Bluetooth (Also Amazon) and it too could communicate, but not Pull the Code. As of now i might consider paying the little Extra $$ for the Software, since this device can communicate with all of my Vehicles. This is my opinion on this. Another thing i found that was Really nice is, when it pulled the Code, because i still have Wifi on my Laptop, it pulled up some Website to help guide me also with locations & Fixes, Really Nice. Well Done! . (Posted on 8/16/2016)
Works With AndroidReview by Amazon Customer [Amazon Review]
I purchased this product for use with my Google Nexus 7 2012 tablet. There is not much information online about whether or not this product will work with android but I can say that it does. I purchased the app Torque on the Google Play Store, set it to USB mode, and disabled slow connection mode and it connected to my car within seconds. I was able to read live Engine RPM, temp, boost, fuel flow, and much more. It will also display ECU fault codes on your tablet This product works great for Windows AND Android so if you are looking for a fast connection between an android tablet/phone and your car, this is the product for you.

though the scanner itself may be just fine, I never got far enough in the setup ...Review by Kay [Amazon Review]
This one gets many, many stars. I had originally tried one of the iSaddle WIFI Wireless OBD2 scanner, and, though the scanner itself may be just fine, I never got far enough in the setup process to find out. This one, on the other hand, has simple, direct, and clear instructions. In fact, it only has 6 steps (effectively, it has 4 steps as two of them are "plug into car," and "turn car on"). The device is just as it appears in the pictures. It has a little LED light on it, and THE DIRECTIONS INDICATE WHAT THE VARIOUS LIGHT COLORS MEAN (double points!!). The instructions direct me to a website to get the drivers/software to run it, and even gives me the validation key for use (TRIPLE POINTS!!!). The wired USB connection ensures the device is actually talking to the computer. Don't get me wrong, I'm perfectly happy with wireless devices, but the plug-in nature coupled with the easy instruction manual makes this a good purchase for a DIY mechanic like me. I don't need a device that I have to first solve like a scrambled Rubik's cube, so I can fix my broken car (my car is broken, you really think I'm in the mood for a puzzle, iSaddle?).

I give this little guy 3 stars for the product, because it does what it is supposed to, and the other two stars are earned by the great, and simple instructions to get setup. Thank you for investing in ensuring that I'm focusing my diagnostic efforts towards my car, not my tools. (Posted on 8/16/2016)
I'm pretty happy about itReview by Trevor [Amazon Review]

I made a video reviewing this device. It works really well for what most people are looking for. If you're looking for more, you can absolutely get more by going with the professional version of the software. It has flaws, but most things do. I'm pretty happy about it. I would recommend it to my friends.

I work on the ambulance, and we have trucks that get a check engine light on all the time. By using this we've been able to find out whats wrong. (Posted on 8/15/2016)
Nice but doesn't allow full use of GM add onReview by Serious DIY
Works great, but doesn't support SW (single wire) CAN which is needed to connect to my restraints control module on my 2009 GM vehicle. You need ObdLink MX to do this is what I found by reading the forums. (Posted on 1/30/2015)
OBD Link SX Scan ToolReview by Neal
This OBD scan tool works great with myt 2005 GMC 2500HD pickup. Haven't tried it with other vehicles yet. I purchased the Enhanced GM Diagnostics and am very happy with the hardware and software. Highly recommend this tool...especially now that they dropped the price $20. (Posted on 11/3/2014)
Very good tool, need PC and does not connect to Honda Odyssey.3Review by Raymond
Have the ODBLInk SX USB and it gives a lot of good information and logging ability.

This is expected, it is a bit bulky to use due to PC requirement. You can try and get it on android, not sure how that works.

Tried it on Honda Odyssey 2008, and 2009 and was not able to fit it. Either the pin on this device is too big or ODB II connector on the Honda had holes too small.

Does Scantool have a version with smaller/thinner ODB II pins ? (Posted on 10/23/2014)
