The socket includes the RAM 1" patented rubber ball and socket system, with adjustment points at both ends for infinite angles. The X-Grip cradle is spring loaded and has great holding power, and also lets you insert and remove your phone very easily.

Timely supply. Item appears to "stick" well to car windscreen.

Great Product and service

I ordered the RAM twist lock mount and X Grip holder for my work vehicle. Placed the order online on a Sunday. Then decided I needed to add a longer extension to my order, so called to add to my order the next morning which was no problem and the staff were very helpful. Received my order a couple of days later which was great. Mount to the window and adjustment took about 2 minutes and it hasn’t moved since. So quick and easy to put phone in and take out. Fantastic product.

Best mounts made

After years of having cheap and mid priced phone mounts fail or regularly come unstuck often with horrific results I decided to bite the bullet and purchase a RAM mount. Honestly this was the best decision I've made, the suction cup grips so well and the X mount cradles my phone beautifully. Without doubt these are the best cradles on the market and by far and away the best made. They are not light but they are very sturdy. I took mine out on the first day for some fairly intense off-roading in my 4WD and the mount never missed a beat. I will be buying again for sure! In summary: Pro's: Extremely well designed and robust, great adhesion from the suction cup. Con's: Cost.

Phone holder

Probably the best most stable phone holder on the market.

So Good

Did not trust my other phone holders. I swear the last was scratching the corners of my Jet Black iPhone. Taking no such chances with my iPhone X though even though it’s glass it has polished steel on the sides. So I bought the aptly named X-Grip phone holder which has 4 rubber holders in the shape of an X. Not only does rubber grip the phone tightly they’re sloped inward so the phone cannot slip out. It was delivered next day! Happy to recommend these people and their products.
