Review on Adapter Rotating Universal Smartphone Mount，Fits Camera & Photo by Tammy Strinden

I have no problem mounting my iPhone 11 to a music stand or bike. But it doesn't fit 9.7 inch iPad as you can see in the picture, using one grip is too narrow and using both grips is too wide. I've tried an iPad Pro 12.9" with an Otterbox case and it works, but I don't know how strong or durable this thing will hold the weight. Generally speaking, it fits the description of 4.7"-15.6" not to!
