It's not bad, but it's definitely not high quality.
The installation was quite difficult, but that has to do with the car and its air vents.
The build quality is mediocre with cheap and hard plastics.
The stabilization mechanism is okay and the phone doesn't fall off in potholes, but you don't feel completely secure.
In short, it's a case of "you get what you pay for."
Does it do its job? YES.
Is the phone stable? YES, but you feel like it might fall off in every pothole.
Do you trust it? NOT really.
Is it high quality? NOT at all!

Very good product for its price, worth it! The only negative for me, that's why I gave it 4 stars, is that the phone doesn't attach very well to the case but the device still works while driving.

Sturdy construction.

The phone easily fits in and is removed even more easily compared to other mounts.

The phone (6") fits without any problem and charges while on the base without any issue with the cable.

It is very stable even when driving over bumps.

I have had it for 1 month with several hours of driving and it really is the best investment (gadget-wise) I have made in the car.
It is stable and even in normal potholes (not huge potholes) my phone has never fallen.
The huge plus is the ease of installation and removal of the phone with one hand, thanks to the mechanism that keeps the sides open with springs and the bottom raised. When you place the phone with gravity, it goes down and the mechanism closes/tightens on the sides.
It also has a hole at the bottom for the cable, which is very positive because you can easily place and remove it with the cable.
