For Colourful Personalities
What it is - the SideKick 360 - is a bracket that mates a mobile phone to a tripod. There is a pair of screw-clamp jaws that sits either side of the phone and gently grips it while the whole rotates on a ball-joint mount. The base of it is aluminium with a choice of 1/4", 3/8", and Arca Swiss foot mounting. You can mount the phone in landscape or portrait orientation.
Useful? Well, if you are a phone shooter, yes. You'll get to use longer exposures ad get steadier shots. It will let you stand your phone on a tabletop or a cistern for a selfie and leave your hands free to make gang signs.
You could mount it on the dashboard to allow hands-free.
