The CYBEX Sirona S is the only Convertible Car Seat in the U.S. to feature an innovative 360° rotatable seat with load leg stability, linear side impact protection, and SensorSafe™ technology.

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.

Outstanding! 5 Stars for Mobility, Durability, Functionality and Ease of Use.
This little invention is outstanding! It holds phones of multiple sizes very securely in place without any bonding or sticky attachments that could damage your vehicle. Mobility is simple as it's easy to add and remove to any vehicle with air condition vents. Best of all, various size devices can be easily held in place with a quick squeeze of the side mounts and just as easily removable with a single press of a release button on the back side. The mount is also very strong and holds up to various temperatures. For example, in the summer it can become very hot in an enclosed vehicle and this mount holds up when other mounts tend to fail from over exposure to heat. The failure causes the joints or fittings to loosen, which will cause your device to slip from an intended position. Well, that is not a problem with this one. It has stood the test of time as I have used this mount for over a year in extreme environments. In the end, it appears that my family has come to like this product too. Ahem, my wife just took mine! So, I have returned to purchase another one for myself and two more for my daughters. Then I don't have to worry about my daughters taking mine either. Yes, I'm finally thinking ahead, so maybe you should think ahead and get additional copies for your family members. Either way, try one and you'll likely be back for more. It makes a great gift. I highly suggest this product to everyone who needs a mobile device mount for their vehicle.

Excellent Product and Exceptional Quality and Service – Highly Recommend!
I recently purchased the LISEN Car Phone Holder Mount [Military Stable] and couldn’t be more impressed! From the moment I unboxed it, I could tell it was built to last. The design is sleek and modern, and it holds my iPhone 15 Pro Max securely without any wobbling, even during bumpy rides. The military-grade stability lives up to its promise—this mount stays firmly in place, and the adjustable clamps fit my phone perfectly.
What really stood out to me was the ease of installation. It attaches to my car vent effortlessly, with no tools required, and doesn’t block any air flow, which is a huge plus. It’s also compatible with various phone models, including the latest iPhone 16, so I know it will be a long-term solution for my future upgrades.
In addition to the great product, the customer service from Linsen was outstanding. They provided timely and clear communication, answering all my questions before I made the purchase. It’s rare to experience such excellent support these days, and it made my buying experience even better.
If you’re looking for a reliable, sturdy, and easy-to-use car phone holder, this is the one to get! https://www.amazon.com/dp/B0CXLQDY5B Highly recommend!

Well made, but not a good fit for Volvo XC40
One issue with this style of holder, is that the swing arm and holder add a fair amount of weight and extends that weight away from the vent, applying quite a bit more leverage on the vent. It may not be as much of an issue on horizontal vents, but the vertical vents on an XC40 will want to swing side-to-side with all that weight.
As for the build of this particular holder, my only real gripe is the adjustment for the swing arm - after tightening the knob, there will still be some play in the arm...you have to jiggle it while tightening it down to fully secure it. The position of the release button allows one-handed removal of the phone, but really only works by pinching with your thumb on the screen. The clip for the vent accommodates relatively wide fins and the tabs can be rotated to help with stability or removed to provide more clearance (though rubberized tabs would be much more helpful).
