With these tools, you never know what you're going to get. And I bought another one, which I've had terrible luck with. I ended up using this tool to fix another one as it failed to get the sensor codes. It was very easy to use. I had all the codes I needed in about a minute. Just a few clicks and then I went to each wheel and I got the codes I needed. I was really shocked that it was that easy as I had been trying to get something else to work for almost 2 weeks. Definitely worth it.
