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

Works great! It’s been a fantastic upgrade for my car. The installation was quick and seamless, and it fits perfectly with the Tesla interior. The wireless charging stays fast and stable. I highly recommend it.

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.

This worked perfectly in my vehicle making hands free driving easy. Installation was very simple, easy to charge my phone in this mount. Very stable, my phone never fell out or off.
