Negative Positive
Title: terrible product
Review: I have been using this for a few months now and I have to say if you want to always wonder if you can even open your gas tank buy this. The key never works so you always need to cross your fingers to see if you will be able to refuel. its awesome!Additionally, it says it works with the audi a4, and no it does not. It screws onto it, but the seal is not perfect and the car gives an indicator that something is wrong.do not buy.
