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)

OBDlink SXReview by Legacy Man
I was very impressed with this scan tool. Compared to the handheld scan tools that cost four times as much, this tool will give you multiple codes. The handheld devices only give you one at a time. It makes it difficult when you repair something then a different code shows up right after. For the price you can't beat it.

excellentReview by mike
Best $50 I ever spent. It was up and running in 5 minutes. Connected straight away to my wife's Santa Fe. My old unit couldn't do it. Great value for the money.

Ford Software Add-onReview by Bert Ruedisueli
Very good service I bought a OBDlink SX and software ScanXL Standard with Ford Enhanced Diagnostics Add-on. Unfortunately, the Ford Enhanced Diagnostics Add-on didn't work since my vehicle was European. After a few emails I got my money back for the Ford Enhanced Diagnostics Add-on. Super service and super fast delivery to the Netherlands.

Very Good! Review by Gray Rider [Amazon Review]
Needed an OBD data reader to determine if any fault code to explain random engine shut down when driving my 2002 Chrysler Sebring 2.7L V6. Think that a software-based tool is superior to a hand-held, as program can be updated, and available data not limited to the size of RAM/storage in a hand-held. Installed drivers from enclosed CD, but could only install program from web - which is probably better since I now have newest version available. Was also worried that Chrysler refers to OBD III data tool in their repair literature, and this item is only an OBD II type - but found OBDWiz gave me sufficient information. Also found that selecting type/speed of communication connection manually enabled me to choose the setting which provided the most data output - the auto-connect selection seemed to just give RPM data. With correct selection, tons of info available, and especially gave me fault code (P0340.) Note that OBDWiz and website gives you only generic info (i.e.: "No Cam Signal At PCM"), but no vehicle specific solution to the problem - just the generic manufacturer fault code description above. Thus, I will use the above info in conjunction with my paid subscription to AllDataDIY.com, which gives me actual instructions for testing, removing, and replacing the Camshaft Postion Sensor and related circuits. Nonetheless, the OBDWiz program and data cable provided exactly what I need and worked fine. Beats paying Chrysler or a garage $ 100 to $150 for just the fault code diagnosis, and probably another $200 or more to replace a $40 part which should take me 5 minutes to remove and re-install.

User RatingReview by Big Daddy [Amazon Review]
After purchasing this tool, I compared it to my standard ODB II hand held scanner with much success. Not only does it have all of the functions of the moderately to expensive hand held scanners found in most auto parts stores, it also allows for live date collection at a fraction of the price. Having a laptop or equivalent is necessary when using the SX SCAN Tool, allowing for data collection and storage. I was able to view live parameters and see real time changes other scanners can't see.

OBDWizReview by John H Mason [Amazon Review]
I have to state that I am extremely pleased and surprised how well this device worked out of the box. I'm not a mechanic and cannot rate this against any other, perhaps better product. I installed the drivers, software, and got an update for it, and then hooked it up to my car. It would not connect on port 3 so I was thinking, "oh, here we go," but it connected quickly on port 4. Showed me everything my car was doing, gave me the code for my check engine light, and allowed me to clear it. Great! I recommend this for those of us who are not mechanics.

Better than most handheldsReview by Eric Caskey [Amazon Review]
This software is great, much more info than most scan tools costing 4 times more. You won't be sorry. I have used it on my daughters Pontiac, my sons BMW, and several of my cars, no problems.

FANTASTIC TOOL!!! Review by Mechanic [Amazon Review]
Just received my OBDLink SX scan tool today and used it. It took me less than 10 minutes to install the software on my laptop and then plug it into my 2002 Ford. After reading the error code that informed me of an excessively lean fuel mixture, it took me perhaps 5 seconds to realize that the EGR valve was stuck open. I cleaned the valve and replaced it, after ensuring it was still functional, cleared the error code (YES, you can indeed clear error codes with this wonderful tool), and the car now runs great again.
The OBDwiz software seems flawless.I can't imagine a better, or easier to use, scan tool. It seems to me that Microsoft has a lot to learn from ScanTool.net in terms of a conscientious work ethic. WELL DONE, ScanTool.net!!! Thank you.

Fast Customer ServiceReview by Luckytii7 [Amazon Review]
Easy product to work with and does as it should. plain and simple. Customer service on the other hand I'm very impressed with - I recently had to wipe my hard drive and everything on it so in turn the OBZWiz software was gone. After reinstalling the software I searched high and low for the activation code - no luck. One request to ScanTool.net with a copy of my invoice and within 5 minutes I had a new one at 8pm. Thanks ScanTool!

Great Product!Review by Brian Lawson [Amazon Review]
I bought this because my 2006 dodge Durango kept showing the check engine light. Instead of paying for someone else to check the engine codes, I wanted to do it myself. This scanner let me know that the O2 sensor was bad and I was able to fix it myself without needing a mechanic. AWESOME!
