The Looq DG is the best self ie stick of all we tested. It has a wired connection — it plugs into the smartphone’s headphone jack to trigger the shutter release. That feature is the Looq DG’s biggest strength, because it eliminates the need for charging or replacing batteries and it doesn’t add Bluetooth- connection complexity. Compared with other wired self ie sticks we tested, it extends to a longer length ( 45.5 inches), collapses to a shorter one ( about 1 foot) and weighs only fractions of an ounce more than the lightest stick of the bunch. Connecting the Looq DG to an iPhone or Android phone is as easy as it gets. A coiled cable plugs into the handset’s headphone jack. A button on the stick’s handle triggers the shutter in your phone’s camera app as instantaneously as if you’d tapped directly on the phone’s screen. The Looq DG uses an expandable C- clamp that adjusts from 2.2 inches to about 3.5 inches across enough for an iPhone 6 Plus in a case. In testing, the Looq DG’s grip was totally secure thanks to the clamp’s f irm tension. The cradle is easily adjusted using a plastic knob to tighten and loosen the mount.
