5 Stars
The size makes it very useful on my motorcycle.
I mounted this diamond shaped ram mount onto the hardware supporting the fairing on my 1977 Harley-Davidson FLH 1200. The size makes it very practical for attaching to limited space. It's strong enough to support my Samsung Note 9 phone. I think this application looks right at home with the vintage motorcycle that it's used on.

5.0 out of 5 stars Mount is sturdy, ball is grippy, a little larger than I expected
Reviewed in the United States on January 14, 2024
I mounted this to the back of a cell phone mount/battery pack. It was a bit bigger than I expected, the spacing between the screw centers is 1.9", the overall length is 2.5". This appears to be molded in a single part but the ball part is coated in a very grippy substance. I have only ridden with it once but it is holding up with a fair bit of weight on my dirt bike.
