## Customer Reviews

### ⭐⭐⭐⭐⭐ Works as advertised
*by S***E on October 4, 2023*

There's not much to say besides, it works as advertised.

### ⭐ Weak ball to shaft connection!!!
*by G***S on September 20, 2025*

Poor construction quality, ball on end attached to my phone ( Samsung 21fe ), broke off during first ride on the street bike. Mounted to the handle bars. That's a bit of a distraction driving down the freeway at 70 mph. Fortunately, I caught my phone and didn't damage anything else. Going to try an aluminum one, wish me luck!

### ⭐ Cheap plastic and not at all tight in a Garmin GPS
*by D***D on September 7, 2024*

This is attempt No. 2 at finding an adapter to mount a Garmin GPS on something other than a glass windshield. These two items are cheap plastic that would break with a twist and don't even fit tight in the ball mount on the back of a Garmin GPS. If you have one, you know how tightly they snap in and how you cam move it and it will hold. These do not fit tightly and the Garmin dangles loosely. Returning. Not usable, especially not for what a Garmin GPS costs.
