The Pocket Tripod is designed to fit snug with the device placed in it. This is necessary to provide smooth and precise angle adjustments. To accommodate for the large variations in device thicknesses, we plan to manufacture a series of adapters, which can be used to achieve the best fit between the device and the Pocket Tripod, for most variations. The Pocket Tripod is not limited to only Apple iPhones. In fact, as long as your device fit any of our existing adapters, it will work just as well. However, it should be kept in mind that certain devices may be heavier or larger than the iPhone, causing instabilities at certain tilt angles.
