Review: Turned on every single dashlight in two of my cars and wasn’t able to remove it. Had to use my other $200+ machine to remove it all.
Review: I plugged it in, and it worked. There were many different screens where you can scan different components of your car. It said everything was okay on my car, so I can't say it caught anything, but I do maintain my car. It is a handy item to check on things if you are worried there is a problem. You just scroll through different menus and check things from the battery to sensors to general issues. The little pamphlet guides you through how to get to the different tests. It works fast with the press of a button. It was compatible with my Toyota Yaris. I think it is cheaper than having a mechanic to screen your codes, though they will do that if there is an issue. I have seen these costing a lot more. So for only $30, it is a low cost option. It is convenient to keep it in your car or home to run out and check any time. You can get a free scan at some auto parts stores, but it is nice to be able to do your own and even compare.
