Highly recommend!
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
It’s all metal! Even the arm that holds the phone!!! All metal!!!!! No cheap plastic! You can drill or clean and stick. 2 for mounting. No more breaking air vents and suction cups cheap plastic that falls off the window or rear view mirror holder that blocks your vision. This is definitely worth the money.

The concept is great, the item is sub par.
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
I bought this for a 2021 Silverado WT thinking I'd be able to screw this into the dash cubby as the adhesive wouldn't servive -50⁰ F Fairbanks winters. Beware, if you own this truck, you have to remove the entire dash assembly to include instrument cluster and infotainment system in order to screw this into the cubby. The cubby on this model is actually apart of the entire upper dash panel and cannot be removed separately as the instructions state.
I decided I'd give the adhesive pad a try until I bought some self tapping screws but the mount is not contoured like my cubby, therefore it badly rocks.
I don't recommend this to anyone with a 2021 Silverado WT unless they want to spend over 3 hours installing this.

Expected more for the price.

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!
