Actually the thing at your provided link was the Ram screen magnifier. Brilliant!!When I was looking at the X-Mount, I heard that there were issues with the phone coming out of the cradle as well as the cradle itself rotating/turning from vibration. Someone recommended this mount to me and I am using it instead for a Samsung S4 in an UAG case. Works great and is very solid! Adjusts to many phone sizes and will work with cases too.....
