Solid all-metal build. I got it for my motorcycle so I needed something more secure than for just a bicycle. This one appeared to fit the bill. The only issue is that it doesn't fit my phone due to the phone's shape and the holder's small curved clamps. While I think this product is well built and a good value, it won't fit all phones so beware. It will fit an iPhone 7 with a standard case. It will not fit my Kyocera Duraforce Pro (no case bc phone doesn't need one). I'm keeping it for future use with a different phone.
