Review on Octo Mounts Universal Smartphone Holder Adapter Kit: Your Versatile Tripod and Mount Accessory for iPhone, Samsung Galaxy, Android, BlackBerry, Pixel, and HTC! by Corby Muin

Let me start by saying that my phone is an exception and really isn't the best choice for a phone with a lot of buttons on the sides of the phone. The kit is clearly not to blame. Plastic - Plain plastic, typical of cheap professional mounts. The spring tension capacity is very strong. This should be an inexpensive solution for most phones.
