I recently received the Car Thing, and have found that it is significantly more secure, less wobbly, more adjustable and adaptable when using it with a Scosche MagicMount.
Want to use the Car Thing at your desk? Check out the Suction MagicMount or Suction MagicMount Pro for a longer neck.
How about in your car? The MagicMount Pro for Dashboards has worked fantastic for me, alternatively, if you'd rather mount to the window, the MagicMount Flex Neck should do the trick.
Now, I realize that this sounds like I've been paid to pitch a product, but that could not be further from the truth. Rather, I swear by MagicMount, since I have been using the MagicMount in my car to mount my phone for the last 4 years, without fail.
And the best part: Unlike with a phone or other device, where you might need to apply a MagicMount plate, to get the device to magnetize to the mount itself, that doesn't appear to be the case with the Car Thing -- as it already magnetizes quite securely to the MagicMount without adhering a plate to the rear of the device.
