Charges slowly and makes phone/charger really hot.
Color: 2White
I thought these would be great, but they aren't. I use them with a 25w charging block, but they charger my iPhone so slowly! I can't really use the phone for any games or even scrolling TikTok while the charger is on it because the phone uses power faster than these mag-chargers can charge the phone. The phone also overheats when this charger is on it.
Never had that problem with a lightning charger.
Basically these are only good when you won't be using the phone, and it takes a long time. Not very happy with them.

Secure Mount With Premium Feel
This phone mount feels incredibly sturdy once installed. No shaking or movement while driving, even on rough roads. The design looks clean and factory installed instead of bulky like a lot of other mounts. It holds the phone securely and keeps it easy to access for navigation.

Good Solid Mount
Got for my 2019 TRD Off Road. Works great, solid mount. Phone easy in, easy out once you get used to it. Looks and feels well made.

Solid Product
I was a bit skeptical based on the price ($85 total after taxes) but you can tell that for the price, this thing is sturdy and high quality. Holds solid onto the vent and keeps my iPhone in place. Easy to adjust and move to your liking, also easy to turn 90* and have your phone sideways. Only drawback is that is obstructs the view of the clock on my 4Runner and slightly obstructs my windshield, but I am sure I will get used to it.
