We go threw these like crazy cause most of the ones do not fit so good our pop out. well this one is made different and stays in no matter what. it also has a couple spots to put our charger in.. cause sometimes we fight over who can use the charger in the Duramax well now we don't fight to the death lol..... I've had this for a while now. and i realy waited to see how it handles and works before i wrote a review. well i absulutly love this brand... you will be very pleased with this.
