  • Update
Update- it turns out my fuse was bad that powers this. It works great! Im sorry for the bad review! POS does not work. I know how to use a scanner, this one is defective though. It receives no power when plugged in. I looked up the troubleshooting on this model and the company says to remove the batteries and reinstall them. IT DOESNT EVEN TAKE BATTERIES. Geez, you just can't get much worse than this! Now I have to go out of my way to return this stupid cheap junk. I do not eecommend! ... show more
