super strong hold!
Style: MagSafe Phone Holder
super easy to set up, holds really tight, and does little to no movement when hitting bumps. magnet is strong enough to keep the phone in place while driving, but weak enough to not feel like you're ripping the mount off the dash. i will say as a warning, find your spot, double check all the things around that might move so you won't impede it (my shifter got close) and dry fit it to make sure any position you will want it in won't be an issue there. i have a similar one in my truck and made the mistake of putting the mount in a spot that doesn't let the phone go where i want it when turned sideways. as carpenters say "measure twice, cut once..."

Powerful Magnet and Total Adjustability
Style: MagSafe Phone Holder, Style: MagSafe Phone Holder
This magnetic car phone holder is an absolute game changer for any vehicle or gym setup. The 720 degree rotation and foldable design allow for the perfect viewing angle every time, and the suction cup is incredibly strong on both the dashboard and windshield. The magnets are powerful enough to hold a phone securely through bumps and turns without any slipping, making it a reliable choice for the newest iPhone series or any Android device. It feels sturdy and professional, offering a sleek look that does not clutter up your dash. If you are looking for a high quality and versatile mount that stays exactly where you put it, this is a fantastic investment.

Perfect for on the go use.
The Lisen Wireless charger is perfect for on the go pop in and pop out when needed. It’s very functional and only needs one hand use to lock or unlock. It fits perfectly on the air vent. It’s look sleek and well made. The charging speed may be slow unfortunately.

Good, except for release button placement
This works well. It’s easy to install, charges your phone well, and mounts to the vent securely. Simply set your phone on it and squeeze the arms to grip it. I like that it’s manual, so you can open and close it even without power. However, the release button is centered on the back, which means that to press/squeeze it, you have to put your thumb right on the middle of your phone screen. It can interfere with whatever I’m using my phone for at the time or just wake it up unnecessarily. Not a huge deal, but it would be great if they moved the button to the side so you can squeeze side to side to release the grip, rather than front to back.
