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.

Great product if you’d like to talk and keep your phone charged at the same time
I really really like these. I have two one in my truck one in my car I like it because I can put my headphones in while it’s being charged so I can talk on long drives like four hour drives and the battery never goes dead and I have the ability to utilize the plug-in. I don’t like Wi-Fi. I have a tendency to lose them so I like old-fashioned wire it just is my preference.
