    Great product!


    I’ve been using a combination of RAM mounts for a few years now on the Yamaha Vmax motorcycle, 24′ pontoon boat, 2016 Chevy High Country pickup truck and Jeep Liberty. I’ve never even came close to losing a phone. The Note4 in an Otter Box case is what I’ve been using day to day. Very secure cradle with very sticky rubber that meets the phone. I’ve added a wrist tether to my Note4 case and when travelling long distance I have a Red Pepper water proof case with tether. You’ll never lose the cradle so throw an attached string tether over one of the 4 arms for an added measure of security that in my opinion, isn’t really needed. My reasoning is in case I wipe out, I can find the phone tethered to the bike.

    Those that have lost phones, the problem might be with ordering the RAM-HOL-UN10BU-NTSU. This version has no rubber tether supplied and is the older version of the X-Grip. There is no RAM Mount logo in the center is how you can tell which version you have. You also need a case for the phone which brings the phone forward where the rubber arm tips can contact the phone adding the needed resistance.

    RAM Mount parts owned at present:
    2x RAP-B-200-2U , Plastic Double Socket Swivel Arm with 1 inch B-Ball
    3x RAM-HOL-UN10BU , Universal X-Grip IV Cradle with 1 inch B-Ball (and tether)
    1x RAM-HOL-UN7BU , Universal X-Grip Phone Cradle with B-Ball
    2x RAM-B-224-1U , Locking Suction Cup with 1.0 inch Ball Metal Plate
    1x RAM-B-367U , Motorcycle Handlebar Clamp Base with M8 Screws
    1x RAP-B-400U , Tough-Claw Universal Quick Release Clamp Base 1 inch B-Ball
    1x RAM-B-201U , Medium Arm B-Socket
    I’m not associated with RAM Mount or Twisted Throttle. Just a happy customer of RAM Mount products.

    Lost my Note 2


    This phone holder lost my Note 2 on the first ride. Very disappointed; RAM’s older style holders were great.
