Does the job - was DOA, but fix was simple
I would have given this five stars, but mine was dead on arrival (DOA). Operating these devices is very simple. You just plug it into the OBDII receptacle under your dash and it should instantly display the opening menu. Mine did not, so rather than return it, I removed the four assembly screws and opened it up. I was looking for a cold solder or disconnected wire. What I found was that the processor chip was simply not seated in its socket. I gently pressed it in and closed the case. Problem solved.

This unit is a good value overall. Of all the code readers to choose from, this one has the ideal features for a home user and it is hard to beat for around $65. Don't let the fact that mine was DOA deter you. These things are very simple devices, and an unseated component is one of the more common causes for this sort of out-of-the-box failure for any electronic device. I would not have made it part of this review, but for the hope that it might save someone else the hassle associated with returning items through Amazon.

Big money saver!!
Recently my check engine light came on in my 2002 Toyota Highlander. This has been the third or fourth occurance since purchasing the vehicle as new. The Auto Scanner accurately diagnosed the code and saved me $89.95 in diagnostic fees at the dealership. The service writer still tried to pressure me into having the diagnostics run, but I stood firm and refused the service. Having the scanner is a real confidence booster when taking your vehicle in for service.

Workable
Bought the reader a month ago, use it regularly as I'm still fighting trouble codes on my 2000 VW
The code descriptions are very basic, you could easily find them (descriptions) online or at an Autozone, so now I think it would have been a good idea to buy the smaller, pocketable model, with the very basic features, thus saving $30 and storage space in your car.
As of the reader itself - it works perfectly, menus are intuitive and convenient.. the only reason I'm giving 4 stars - my personal doubts if extra functionality worths extra $30 and a bigger size.

Autoscanner Works
This is a no frills device that does exactly what the box says. I was able to pull the code from the car, diagnose the problem ( in this case, replace the thermostat ) and then reset the codes. The repair cost me less than $20. I am not sure how much a automotive shop would have charged but I am willing to bet I came out cheaper. And that was the first time I used the scanner.

Exactly what you want.
Plug it in, turn the ignition to on, and in about 10 seconds you'll be able to see the codes.

Press a couple of buttons, the check engine light goes out.

Everything should work this simply. Will easily pay for itself with a couple of uses.
