The MOTORBUDDY Emergency Breaker let me DOWN during an incident making me doubt its quality and durability. Based on my experience, I wouldn't recommend it to anyone in need of a reliable automotive safety tool. While it fits nicely into my car`s interior accessories, it failed to perform when needed most .The only pro is that it's easy to install and doesn't take up much space. Unfortunately, the con is that it simply doesn't work when you need it to..
