this little guy does an awesome job, it is very smart. I love how it actually shows you exact codes. It's easy to use and sets itself up pretty much by itself. This is definitely something anyone can use. This looks like the top dollar more expensive products that you see, especially at a dealership. I highly recommend this item. I am having to learn things on my own now that my hubby is sick and bedfast. He is awaiting lung transplant so he cannot do the mechanical work he used to. I find this very useful for me.
