Expected more for the price.
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
Arms are a bit short, and within a week, I could already feel the springs feeling a bit ridged. Holds well and does the job. Looks nice to!

Nice, and would buy it again
Style: Qi2 Charging Mount
So far I'm liking this product. For the model X, you can use it on either side of the screen. As well, it holds on very well on the screen. Very good build quality and design. Fits perfectly to the screen. Very strong magnetic fit. But can cause scratches to your case if tth case is a hard plastic material.

Not perfect, but good enough for daily use
Style: Qi2 Charging Mount
Well made and very strong magnet. Make sure you tighten it completely or it will fall off. The tightening screws are not intuitive, but after some confusion you can figure it out. Works as intended and charging is as fast as your phone allows.
