Review on Side Mount Phone or Tablet Holder: Transform Your Laptop or Computer Monitor - iPad as Extra Display for MacBook - Portable Dual Screen Setup - No Clamp, Clip or Intrusive Design by Tristan Graham

I use two to attach a surface pro 4 to my lenovo yoga c940 and it works great. Each pack contains 2 rectangular mounts and 2 circle mounts, so you can easily attach one to an additional device such as a phone. They don't feel cheap at all and I don't have to worry about clips damaging my screen. I doubt I will have to replace this system in the years to come. Replace any of the metal plates, the ones I replaced have your device's surface protection, no punched holes and adhere much better than the ones supplied.
