Absolute trash.
Color: 2White
Neither charger worked on arrival... Quite disappointed. Now I'm steering away from every item that has the same markings. Just shelling out for a better quality charger... Not worth it at all... It's incredibly irritating having 2 DoA chargers... Tried on 5 different phones and 10 different blocks.

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.
