## Description

Ideal for vehicle windshields, the RAM-B-166-UN10U consists of a 3.3" diameter RAM Twist-Lock suction cup base, medium length double socket arm, and the popular spring-loaded RAM X-Grip large phone holder. The RAM X-Grip features an 'X' design that expands and contracts to provide a perfect fit for your device even if it's in a case. Made of powder-coated, marine-grade aluminum, stainless steel components, and high-strength composite, this large version of the RAM X-Grip fits phones ranging from 1.75" to 4.5" in width and keeps your device completely functional and accessible. RAM ball and socket technology allows for near-infinite adjustability to achieve the ideal viewing angle while also extending the life of your phone by providing shock and vibration damping. For outdoor applications, the RAM X-Grip includes a device tether that is recommended for added security and peace of mind.

Review: It holds the phone very firm - Very good phone holder the best on the market I only buy the best not rubbish
Review: My criteria to buy: cost; will it hold a Nexus 5 phone or Nexus 7 tablet (not at the same time); fit well in Acura TL; multi-use ability for car or bike (still need to buy the component for bike). Other than the cost, its a Winner! If cost are not an issue - hands down this is the tops of all the mounts. Easy use; fast no-fuss setup, rugged construction. Smooth operation when needing any adjustment or when changing out phone or tablet. There were other mount models that are unique design, compact, lower priced (not necessarily cheap material/made) but after long review on the web, the RAM website, and other reviewers, I believe the RAM products are superior in material and construction and effectively functional design. This item was listed in desertcart's Automotive section and didnt have a product picture - almost missed it in the long list of other mounts. Once I found the RAM products, they get high marks and I agree. The RAM products are component based. I specific item was a one item purchase but it has the following components: the 3.3in (larger) suction base with twist lock (RAP-224-1U), 1in ball diamond base adapter (RAM-B-238), 3.69in Double Socket Arm (RAM-B-201), and the RAM Universal X-Grip IV Holder (Large Phone/Phablet) with 1" Ball(RAM-HOL-UN10BU). Didnt want 2 devices for my phone and my tablet and another device for my bike, so I took a chance on this one. There are currently 4 models of the X-Grip, this is model IV for Large Phone/Phablets. I can hold an HTC EVO 4G, Nexus 4, Nexus 5 (with or without cases) and a Nexus 7 (2012 or 2013; with or without cases) (I use the MoKo Nexus 7 Slim-Fit Case). Only hesitation was the price - but considering it meets my tall order. Great deal. I used the Arkon for a long time but it was a beating to use. To insert or remove a phone or to adjust , tab holder would fall off, hard to align, felt like it would break - not this mount. Place suction where you want, turn lock lever, turn knob on arm, align and tighten - base is done. Now grab x-grip rubber post caps with one hand and position your phone or tablet - done.
