Review on Universal Andobil Cup Holder Phone Mount | Stable & Compatible | iPhone 12/11/X/8/7 & Samsung S21/20/Note 20/10/9/7 | Ultimate Car Phone Cup Holder, etc... by Daniel Truett

I was surprised by the product. It feels solid, well made. There's a knob on the top that you twist, and the sides slide out and tighten into the cup holder. They have rubber ends to keep them from slipping. They also have ports for giant cup holders, but I didn't need them. The angle is easy to adjust and I'm very happy with it. One more thing to mention the phone repairing mechanism is great. It is quickly released by pressing the buttons on the side. And below there is a part that you can pull down if you have a big phone. Intelligent design!
