It worked right off, telling me of a minor problem (somewhat flakey coolant thermostat) - an easy fix.
Regarding complaints that the LEDs face down - the label peels off easily, exposing four screws. Removing them lets you pop the top off, rotate the OBD II connector and reassemble. Then they will face up for you.
As far as the LEDs - you don't ever need them anyway. And there's no documentation as to their function. But if you want to know, they are (left to right):
Yellow - OBD II TX
Green - OBD II RX
Yellow - RS-232 TX
Green - RS-232 RX
Red - Power
The TX/RX pairs flash when data is being transferred between the cable's microprocessor and the vehicle (OBD II) or your computer (RS-232). The Power LED lights when the cable has power, either from your USB port or from the vehicle's OBD II connector.
So it does what it claims, it is as future-proof as you could ask (all the software runs on your PC and can be upgraded), it's inexpensive, it's small. Pretty hard to beat!

First step: download the latest software. The vendor ships a mini-cd with the package that contains the software; on the outside of the cd envelope they place a label with the web link to download the latest version of the software, here:
[...] yes, that is the correct URL, and downloading this software is the best approach. Worked like a charm when I installed it following the instructions in the "QuickStart Guide"; it is important to follow the instructions precisely.
By the way, my laptop uses Windows 7 Ultimate, and during the install process you will be informed of the proper "com port" to use for connecting to the hardware, take note of it. Use the AutoDiscover button, then save the settings.
My research revealed that the manufacturer has been shipping hardware version 1.4, but I received hardware version 1.3a from the vendor, which, while disappointing, it's working just fine - as stated earlier, you get what you pay for, and the Amazon item pages never specify the hardware version being shipped. Meh.
This system works fine with my 1997 kia Sportage 4x4 EX. I anticipate purchasing the newer version 1.Read more ›
Only downfall is you need a OBD2 extension cable if you need to drive the vehicle and read sensor data. (At least in my vehicle, 2002 ford explorer xlt - the sensor when connectoed to the port, hangs striaght down, right in front of brake pedal.)
a) the "OBD 2007 lite" software does not allow you to save the data as a record of current performance/system status on your PC,
b) the "OBD 2007 lite" interface output is all purely numeric and does not generate curves documenting engine performance
c) I have not been able to get the prettier "digital dash 5.0" software to work that came on the software disk. It locks-up as soon as I request the Auto-Diagnostics page. Others may have luck with this, I have not.
If you want the more advanced software that should work with the adapter (OBD2Pro by glm software) it will cost an additional chunk of change. ($79 for the software as of this writing)
I am looking for a better software package that will work with the scanner. According to the documentation, the scanner tool is versatile and should work with other packages.
Detailed instructions are included on a PDF on the CD. These instructions tell how to install the drivers for the cable and how to change the COM port, if needed.
The EasyOBDII software works decently well. I would like for all data fields to be displayed at the same time. The program only allows me to look at certain groups of data at any one time. I installed a PDF printer and EasyOBDII allowed me to print directly to a PDF. The program hangs up every time I try to print to a PDF while viewing real time data. I don't know if this is a problem with EasyOBDII or the PDF printer.
I haven't tried out the trial versions of the other software. I intend to do that at some point. Also I'm interested in looking at using the cable with the Linux program called Freediag. It would also be cool to have a look at the included C++ source code. I haven't had time to do these things yet.
By the way, I did purchase an extension cable as other reviewers suggested.
