Great for the price

Obviously you're not going to get a lot of in-depth ratings and deep down specs with such a simple unit but it works wonderfully for the price. I have a catalytic converter that I know needs to be replaced before my next smog check. It's wonderful to have this so that I can periodically check the codes that are firing to make sure there isn't a new coat that I need to worry about. I've used it on my Santa Fe Hyundai and on my Dodge Neon; Great Piece of mind to have some kind of idea of why my check engine light is on!!


very easy to use

Works great! I've used it multiple times for myself and for friends. Its not a cure-all and by that I mean that sometimes you'll get an error code that doesn't tell you what actually wrong. My GMC gave me an error code that suggested the transmission and I had to take it into the dealer. So it won't always give you what you want to know but thats not an issue with the product, thats the automotive industry forcing you to go to them. I love this product and its super easy to use.


Good Code reader!

Works for all my cars, Jaguar, Chevy, Honda, Mazda. Like I said in the title, this works on ever car I own 2007 and up. The price is so cheap and it works perfect. Plug it in, pull the codes, google the codes and find the issues. Can also reset with this.
