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.

Best mount for Gen 2 Tacoma.
Sturdy, fits good, and simple. Can’t close vent, but I expected it and it’s worth the trade-off. Highly recommended.

Worth every penny!
Excellent quality. Very easy installation. Took me less than 2 minutes. Holds phone securely. Looks very good. Easy adjustment. Very pleased. Worth every penny. Highly recommend.
Update: I've been using it almost 2 months and it seems very well made. No issues. Very satisfied.
