This is the RAM mount I use. It’s not the X-grip. https://www.amazon.com/RAM-B-149Z-PD3U-Motorcycle-Universal-Handlebar-SmartPhone/dp/B002KETWIU/ref=mp_s_a_1_4?ie=UTF8&qid=1545776989&sr=8-4&pi=AC_SX236_SY340_QL65&keywords=ram+universal+smartphone+mount&dpPl=1&dpID=314xc04KH8L&ref=plSrch

I have a slightly different mounting system, but this is the piece I use that attaches to the phone. I’ve been using it for a year and a half and I have no problems. It feels super secure.
