A great line of sight phone holder with a few flaws.
Overall this does the job and is priced affordably the pros and cons are as follows:
Pros:
Strong magnet
Solid construction
Great for line of sight
Charges well
Cons:
Charging cable is not long enough to route inside my car
holder tends to droop down slightly with my phone on it (Pixel 7), not so much that it's failing but just not holding it's set position

Does not swivel and slow charger
As mentioned in another review, you cannot change the angle of the phone so it faces the other way since it does not swivel. Wish I wish I would have known that before placing it. Also, the charger is REALLY slow. It’s slower than the MagSafe chargers I have in my house. I’m not sure if this is defective. I only used it on my way home from work, and I will be returning it.

No drilling required
Size: Large
I installed this on my 2021 4Runner with the adhesive provided and no drilling. It has been a few months and it’s still solid. I live in Hawaii and the temps in the car have reached over 100* F pretty consistently and the adhesive has held up very well. There are a lot of attachment points for whatever you want to use it for. I only wish they sold the magnetic mount that it comes with so everything can match up. I use it for my phone and baby monitor. I would purchase this again.

Love this ram mount kit
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121, Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
All i can say is wow. This is an amazing ram mount kit for my 22 Silverado custom. All the hardware is top notch. The metal is all powder coated black with a nice grey American flag. There are so places to be able to mount addition arms. The phone holder it comes with is solid aluminum with a nice tight spring. I rate this 10/10 and for the price you can not beat it or find another better. I didn’t use the adhesive on the bottom so i can’t speak on that but i can only imagine it is really good as well. Hands down is just as good as the super expensive bulletpoint mount you see advertised. Don’t hesitate to buy.

Looks great
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
Fits great and is heavy enough to stay put. I used the adhesive backing to install as I did not want to drill into my truck but it still works well and I have had no issues with it popping out or anything else.
