Arkon Slim-Grip Ultra Mounts for smartphones and tablets review

arkon slimgrip 01

Car interiors are becoming increasingly cluttered places.  When I got my new car, I decided not to mount my phone because I could not find a spot I liked.  When I heard of the new Arkon Slim-Grip Ultra Mounts, I had to take a closer look.  Would this give me more mounting options than I thought of before?

The heart of Arkon’s smartphone/tablet mounting system is the new Slim-Grip Ultra Mount.  It extends a maximum of 7.25″ in a sleek, spring-loaded “claw”.

Arkon packs in eight claw “fingers” of two different depths. Mix and match to find the right combination for your device.

At rest (not under tension) the smallest grip distance is just over 4 inches.

With the deeper “fingers”, that non-tensioned distance is about 5-1/2 inches.

Arkon sent four different mounts for different needs.  Let’s take a look at each one.

Arkon SM614 suction cup mount

The Arkon SM614 suction cup mount resembles just about every other suction cup mount you’d expect for a basic windshield mount.

You get the Slim-Grip mount and fingers, an adjustable suction cup mount, adhesive disk, and instructions.

At the bottom of the mount is a clear, soft plastic suction cup.

The grip snaps together with this two-slotted thingy on the back. No tools required.

This is the mount in full extension.  Notice I used the taller fingers on top, the shorter ones at the bottom.

Since the iPhone’s top button is offset, you can move the fingers to avoid accidental presses.

A closer look at the ball assembly.  Quite simple.

The joint is equally simple.  That’s a metal bolt, not made of plastic.  The hinge has detents to lock into position.

If you want to mount this to the dash, the included adhesive disk can help.

This is the SM614 mounted in the corner windshield of my car.  Check your local laws for mounting restrictions.

Arkon SM679 “sticky” mount

Next up is the Arkon SM679 sticky mount.  It’s nearly identical to the previous SM614, except the “arm” is shaped a little differently, and the suction cup is replaced by a goopy, sticky-as-anything suction cup.

This sticky cup is ideal for surfaces that aren’t perfectly smooth-as-glass, such as most car dashboards.  Try to keep the sticky side clean (avoid dropping it on the ground or on a cat) to maximize grip.  Again, it comes with the round adhesive disk, but you probably won’t need it.  Here it is on my dashboard (not windshield), and it’s not going anywhere.

Arkon SM668 Car Floor Mount

If you need something a little more “installed”, the Arkon Sm668 Car Floor Mount attaches to the floor or seat rail mount of your car with an 18″ flexible gooseneck arm.

All the usual suspects, including a freakishy strong gooseneck bendy arm thing.

When I mean, strong, I mean it.  You really got to give it some OOMPH to bend the thing.  It’s just rigid enough for the car environment.

On the rear you’ll find the same familiar slotted mount.

Two styles of feet are included.  The crow’s foot one comes attached.

Installation is fairly straightforward:  Loosen your seat rail mount and slip the foot in, then tighten.

Some assembly required

…except you need tools.  Not too long ago, my socket set was stolen from my garage, and I haven’t replaced them since.  (Dear Santa…)

Arkon SM6HM3 extending headrest mount

Finally, Arkon has a vehicle headrest mount for your smartphone or tablet, the SM6HM3 Extending Headrest Mount.

The heart of the setup is this clever locking and adjustable claw that “wraps” around your headrest post.  The set screw adjusts for different diameter posts.

This locking tab, similar to those you’d find on a camera tripod, lets you adjust for different headrest post widths.arkon slimgrip 37

Once again, Arkon uses a pretty straightforward ball and socket setup for adjustability.  Note that this ball diameter is quite a bit larger than the other mounts in this review.  arkon slimgrip 40

Thankfully, Arkon’s instructions are quite simple to follow.  I went back to the garage…

…and was handed another defeat.  My car does not HAVE the two-post adjustable headrest.  Lesson learned:  Check before you buy!  I may gift this to a family member who doesn’t have my kind of headrest.  Oops!

Arkon makes some great stuff.  Even if some sticky-fingered neighborhood thief makes off with your socket set or if your headrests aren’t adjustable, they’re bound to make something that suits you.  Check out the full line of Slim-Grip Ultra Mounts for yourself!

    Thanks for the thorough review of our new Slim-Grip Ultra series of universal smartphone and mid-sized tablet mounts.

    Many smartphone users like to keep their phone mounted horizontally. Does this mount work effectively when turned sideways?

  • Andy Chen December 14, 2013, 12:30 pm

    Very well sideways.

  • DracoSolon December 15, 2013, 9:34 pm

    How exactly does it grip the phone? You don’t mention it being spring loaded. Are the arms bendable?

  • Andy Chen December 15, 2013, 10:09 pm

    “It extends a maximum of 7.25″ in a sleek, spring-loaded “claw”.”

    Mine broke first time I used it. Threads stripped where the ball is held in place. Absolute junk, buyer beware!!

    • Aaron July 31, 2017, 1:02 pm

      Sorry to hear yours broke. That’s highly unusual. You can get a replacement by emailing a photo of the situation to — Arkon stands by its products and has a strong 2-year warranty on all items. Some items even have a lifetime warranty.
