It didn't work for me. The rubber at the base was stuck with cheap double-sided tape. It kept coming off.. I gave it away.

Easy installation and use. Keeps the device stable. However, it must fit perfectly on the dashboard, as if the dashboard is not level, the base will not remain stable. It also has a rubber surface to hold the phone steady, but it came off after the first few uses

It slips with the slightest movement and comes off its position. Additionally, at the point where the hook closes and touches the device, the buttons are located, so when I place the phone exactly in the middle, the phone shuts off. If I place it slightly below the middle, the whole "system" leans because the base slips from its position anyway. Once, this was the cause and I almost crashed!

Very good for its price. The negative thing I find is that, because it goes above the dashboard, it somewhat limits visibility in the exact front part of the car. To put it more accurately... it is somewhat annoying. However, it is worth it, especially for trips.

The rubber bands that hold the mobile phone came off on the very first day. Without them, the phone slips away and disappears into the first deep pothole... And unknown to us... Where you can find anything from small items to the neighbor's forgotten cat...

It is easy to store and install. It is moderately stable when placed. Unfortunately, during the summer, the rubber that holds the phone in place tends to come off due to the heat (their adhesive softens) in the sun, and you have to search for them to stick them back on. The horizontal position for the phone (it doesn't fit vertically) is not so convenient for maps, and the position doesn't always have good visibility (the steering wheel obstructs the view in some models).

I will consider getting a mirror mount in the future that allows for vertical placement. Maybe it's better.

The base is good for its price (under 3 euros). However, the part that touches the dashboard is more curved, resulting in it not being securely fastened in my car. The problem is fixed with a little foam to fill the gaps and create the necessary friction, after which it became much more stable.
My phone is securely fastened to the holder. So even if it doesn't fit exactly to the curvature of your dashboard, you can still do this simple trick!
