At least in my car, a T-Roc, it can't stay in place at all. I replaced it with another mount.

Reliable, works for several years without problems, holds the phone steadily (despite the fact that the air vent grilles are not the most stable point to mount a phone holder).

It is good until it is not. The phone can easily fall forward in a pothole, especially if it is large in size. Yes, it is beautiful and easy to install, so for the money, it is fine. Unfortunately, mine broke in the third month, I won't say that it is the holder's fault as my phone is very heavy, especially with the bulky case I have chosen. The system with the clips on the air vents is good but not perfect. They could have more strength when tightening to prevent the whole case from falling on the floor with the phone, it happened to me a few times. Or at least the tooth/stopper at the end could be bigger. If you have a not so big phone and good shock absorbers, buy it.
Update: They released a second model and added a hook to prevent it from falling completely from the air vent. They didn't even listen to me.

Very good application and ease in placing the mobile with one hand

It is good. It simply does what it says.
Easy to install and use.
It just doesn't fit in weird air vents, like round ones.
Simple and practical

For me, it stays in the car, in the air vents that is. It never happened to me that it turned or flew away in the 2 years that I have it.

Wasted money guys... if you fall into a pothole, the phone is gone immediately.... such a shame for the money....! For a good case, you have to spend over 25€ otherwise it's not worth it.....

Wow, this thing with the air vents, when it's empty it sits perfectly, but when I have my phone in it, it leans downwards due to the vibrations. It might be because of the vents in my car, but it's not working for me. It's a shame because it's a convenient case

In the beginning, it was fine... but after six months, the spring at the back loosened and it keeps falling off constantly... not only that, but the hooks also loosened and you have to close them every 5 seconds... I don't know if I got a defective device, but it's not worth it, not even if they give it to you as a gift...

I made it a gift and liked it. He told me that it is user-friendly and stable. The 4 stars because I did not buy it for myself and Cretan is the basis of the person's opinion who made it a gift. Also very economical.

3 stars because the clamps that hold the phone are not stable. Otherwise, for its price, it's okay!

I have it for a few days but it is very stable in the air vent!! Also, the material is good and you don't feel like it will break right away. I especially recommend it for its price.

Previous I had the magnetic one which was very stable but not worth ruining your case with the metallic attachment so I got this one. It holds the phone quite well, no matter how many bumps it has fallen into, it has never come off. The phone I have is 189g and relatively large. The only downside I have is the mechanism which is of poor quality, of course with a little oil it can be fixed. It is a very good and cheap option

From the moment I held it in my hands, it seemed to me to be of "cheap" quality construction, and this was confirmed by the first few rides. With the slightest pothole (and Athens is known to be full of them), the phone would come off the mount and fall down. I recommend choosing the simple magnetic mount for the same company's air vent. I have no complaints about that one.

Good base for a few months of use. Then, the attachment it uses to hold onto the air vent loosens/bends (on both bases I bought) and starts falling very easily on road bumps, making you search for your phone on the floor.

In the potholes not at all stable because it does not grip well on the air vent... And very noisy because it does not sit well neither the mobile phone.. Waste of money..

Very good construction and strong base! Everything is great. The only negative thing that might bother some people is that the base that holds the phone is quite "out" from the air vent!

I put it in the air vent, but after a while it comes out of the vent due to potholes and road irregularities. The build quality is not perfect, you could say it is mediocre. In conclusion, if you want to put it somewhere in the house or office, it's okay

The best value for money.
It holds the phone in a vertical or slightly tilted position.
It cannot hold the phone horizontally.
Sturdy and does not move at all, easy to remove and insert.

Solid construction, easy to install, but stability plays a role both in how the air vent is made and in the size-weight of the mobile device. Personally, I was satisfied

I have been using it for two months now and it is excellent. At first, I had a problem and it didn't stay in place, but once I put it correctly in the air vents, it never moved again. The phone holder needs to be completely inserted. (Unfortunately, the air vent cannot be moved afterwards) By adjusting how it stands at what angle, the phone stays stable and works perfectly. At first, I thought my phone with its case wouldn't fit, but it's fine. Overall, it is a simple construction that does its job and even more, keeping the phone stable and very convenient. One detail is that the car needs to have large air vents, in my smart car it couldn't fit properly.

Very good case. The phone, although about 200 grams, holds it very securely. I have fallen into so many potholes and neither the phone nor the case has fallen.

Very nice, one of the most beautiful for this reason and experience. Perfect application on the air vent. And it seems to have durability. (After some time, I noticed that the grip became slightly crooked, I don't know if it's my fault with poor installation, etc. Overall, it's beautiful and useful.)

Quality, definitely does a better job than those that you have to stretch to hold the sides of the phone in two places and eventually break. Not suitable for more intense driving. It slips on left or right turns.

Very nice and high-quality metal base, completely embraces the phone, resulting in it never falling. Its mechanism is automatic, so all you have to do is leave the phone and it will automatically embrace it from the sides. However:
- You should know that it is not suitable for devices with the large side of the phone, as the mechanism can no longer hold it. The bottom part of the base needs to be constantly pressed, and if you twist it 90 degrees, it will no longer exert force on it and the base will release the phone.
- The air vents of a Ford Fiesta cannot securely accommodate this base clip. It will constantly move with the slightest twist. Fortunately, the base itself can be removed from the air vent clip and can be adapted to another one that you may already have. It is the classic ball system.

I have bought several, this one is by far the best. Practical, sturdy, comfortably fits a 6-inch phone with a case, durable, metallic, elegant design.
