Imperfect, sometimes charging is unreliable, clamp needs power to work and annoyingly not auto
The build quality is great for the price. Like iOttie. The tech advancement is cool but it doesn't work very well which is a disappointment. It doesn't charge my phone very fast, because my phone is limited to 15 watt wireless charging, but it's great for preventing battery loss while using GPS. The button to manually clamp and unclamp are a little too hard to press, it flexes the whole holder, so you need to press with your whole hand supporting the holder. Sometimes my phone disconnects and reconnects randomly to this charger multiple times. Not sure if it's the charger or phone but that stinks . (I'm using an Anker 50w USB adapter for this wireless charger) The clamping is motorized which is cool, but it's honestly less reliable than a spring loaded clamp because it doesn't always auto clamp the phone. When this clamp is working properly it is great as it auto clamps onto a phone it's charging. But the issue is it doesn't always clamp. It sometimes thinks it's clamped, when it's not, so you have to press the manual activation button twice so the phone will be locked in place. It's hard to know when you need to press just once or twice. (The reason you press the button twice is if it thinks it's closed when it's actually open. Then you press first to "open" the clamp, even though it's already open, then press again to close it. But if it knows the correct clamp position already, and just refuses to auto clamp, you only press the button once. If you press twice, you will end up cancelling the clamp. It feels random and unpredictable what the correct action is) The clamping requires power which is another disadvantage to spring loaded hand clamps. But unclamping works without power due to a backup battery. (Powered clamping is still better than those manual squeeze clamps, which are finicky to get a strong enough clamp on the phone) I'm not sure how safe the battery is in a super hot car, like Florida heat. It seems fine for Pa heat.

Great product
UPDATE: Amazing customer service. I didn’t reach out, they did. After some adjustment shaking is minimal. Also regardless the charging. Well apparently my case is not compatible with fast charge. Phone charges fast without the case. Guess that has been my issue with other wireless charges. Definitely recommend. My husband went with another brand and now will be getting the same as mine. Cool idea but definitely not super fast charge. In 40 minutes charged only 10%, was expecting more. Hold phone well but it shakes while driving. Installation was super easy.

Don’t waste your money on this phone holder. I had a very bad experience with it, and it damaged my phone twice. The holder opens by itself without warning, causing the phone to fall out while driving. Sometimes I found my phone under the seats, and other times it dropped while I was driving on the highway, which is very dangerous and distracting. One time, the holder suddenly released my phone and it hit the handbrake hard, breaking the screen completely. I had to spend $500 to replace the screen. The opening and locking system does not work properly. Sometimes it opens randomly, and sometimes it closes by itself. The wireless charging is also unreliable — sometimes it charges, and other times it stops charging unexpectedly. When the charging stops, the holder suddenly unlocks and drops the phone. Overall, this product is unsafe, unreliable, and not worth the money.

Rock-Solid MagSafe Mount—Perfect Fit for Tesla Interiors!
This Tesla MagSafe phone mount is hands-down the best car mount I’ve used. The magnetic strength is incredible—my phone snaps on instantly and stays firmly in place, even over bumps and sharp turns. It truly lives up to the “strongest magnet power” claim. The design looks sleek and factory-made, blending perfectly with my Tesla Model 3/Y/S/X interior without blocking the screen or vents. Installation was quick and tool-free, and the mount feels extremely secure once attached. I love that it works flawlessly with MagSafe and also holds non-MagSafe phones just as well. The viewing angle is ideal for navigation and hands-free use, making driving safer and more convenient. If you’re looking for a premium, reliable, and stylish phone mount specifically designed for Tesla, this one is a must-have accessory. Highly recommended!
