Almost Perfect But With Workaround it Rocks
Style: Dash+Screen+Qi2 Charger, Style: Dash+Screen+Qi2 Charger
This works almost perfectly in my Tesla, with one small tweak for hot summer conditions. It holds my phone very well overall—I position it slightly off-center at about the 10 o’clock position. However, with a larger phone like the Galaxy S25 Ultra, the combination of weight and summer heat can cause the mount to slowly rotate as the suction cup loses some grip. I found a simple fix that works extremely well: applying a small amount of rosin (the same kind used for violin bows) to the friction point where the rotating arm meets the suction base. That added grip completely solved the issue. Now the mount stays exactly where I position it, even in the heat. Solid product, and with that minor adjustment, it performs exactly how I need it to.

Almost perfect
Style: Screen+Charger
Solid mount. I’ve tried other ones but they don’t sit as nicely as this one. It also has a lot of adjustments to allow for using it any way you need it to so it is very versatile. The magnet strength is really good and holds my phone really well. Sometimes it feels too strong which I guess is a good thing. The charging works well but I wish the cable was a little longer

Super easy to set up
Style: Screen+Charger, Style: Screen+Charger
I couldn’t be happier with this car phone mount—it’s easily one of the best accessories I’ve added to my vehicle. The build quality feels solid and durable, with a strong grip that keeps my phone securely in place even on bumpy roads. Installation was quick and hassle-free, and it holds firmly without slipping or needing constant readjustment. What really stands out is how easy it is to use one-handed. I can mount or remove my phone in seconds, which makes a big difference while driving. The adjustable viewing angles are perfect for navigation, and it doesn’t block my view of the road at all.

Poor socket design.
Style: Holder+Dash+Vent+Windshield
Overall this is a pretty decent phone mount. I have used it with both the windshield and vent mounts. The only problem I have is the design of the ball swivel. The socket contains a rubber piece to help increase the grip, but over time heat from the sun or the air vent makes the ball glue itself to this rubber piece. When you try to make an adjustment, the ball will not move in the socket and ends up breaking the socket. This is happened to me twice.
