It seems good, but the quality of the product is average to low; it's very cheap plastic, but overall it's okay.
Very unsatisfied they give you no instruction how to put it together
You can easily attach the phone to the mount. It holds it quite firmly. There are no problems during normal riding. One tip: spraying some WD-40 on the inside will make it more flexible. If you don't have WD-40, you can apply a little Vaseline to the moving parts to reduce stress.
I use the Galaxy 23 Ultra and it fits snugly because there's a case on it. Other than that, it's great. I don't have to worry about the phone falling.
They are so efficient that I already had one installed and bought three more to install the same ones on my two motorcycles and two bicycles.
