        Hey jimelpitt,

        We’re sorry that you are having trouble with sticking the mount to your case. It actually was designed to stick to most any clean, flat, hard surface including phone cases. We have had a ton of success using it with our LifeProof cases. Feel free to give us a call at 1-888-533-0735, and we’ll be happy to answer any questions about this and help out in any way that we can!
