Even though the case for my phone is great and very durable the holster broke the first time i got into the passenger seat of my wifes SUV.This hasn't deterred me from using the case but with the rubber sleeve it can be an inconvenience.
works like a charm! occasionally pops out of waist clip but thats only when bouncing around. I also have a car charging holder for which I have to remove the case for it to fit, small hassle to have all benefits.
