The holder is made by Baseus which is a very large company that supplies accessories for iPhones but also all android phones, this works e.g. for all smartphones with up to 6" screen.

The smart car holder is not like the other car holder we have sitting in your car's air outlet, the others use a spring to hold onto your iPhone, it means it's hard to get it in and particularly hassled to get it out of the holder again , The Baseus Gravity car keeps using gravitation in the form of the weight from your iPhone to hold onto it when you put your iPhone in the holder making the weight on the iPhone that the bottom holder, which is under the iPhone, gets pushed down, the mechanism makes so that the holder squeezes on Your iPhone simultaneously, so that when the holder can't squeeze anymore, your iPhone is stuck, all you have to do to get your iPhone out again is lift your iPhone out of the holder. The system is super smart and simple and it works really well.

Baseus Gravity car holder is perfect if you use navigation from your iPhone while driving, it can sit by your side and guide you through the city or the holidays without ever having to worry about whether your iPhone is stuck or about whether something is happening.

The holder must sit in the air ventilation on your car, it can be adjusted so that it works with all cars because it only has a single holder for the air ventilation then it only needs a membrane where against most others need 2 or 3, the others require the distance between the membranes is the same as they were expected. 

The Baseus Gravity car holder has a ball head which allows you to tilt it up or down if, for example, you have air vents that sit slightly up or down compared to normal. The Baseus Gravity car holder also has a hole where your iPhone's lightning cable can sit, due to the way the mechanism works, the hole for the lightning plug is always in the middle, so there's always room for it.
