I use it to hold my phone in place while I work, and when I lie down or wash dishes to watch videos. Very convenient size, the base section is about 45cm, the middle flexible section is 35cm, and the flexible section is about 28cm. The clamp holds the phone securely. The arm moves a little if you use the phone, but for €12 it is expected.
Tip: if you want to change the angle, hold the clamp to rotate it, not the phone because it will come off.

Quite good, I use it with my phone, I put it on some shelves next to the bed and it snaps on, or in the cabinet when I wash dishes, it's fine. If you have a pop socket on the back, it doesn't have big enough clamps to hold it. I take off the phone case and attach it directly and everything is fine.

The pads it has to grip are starting to come off a bit from the tightening, but damn, the glue is useless. The only point that worries me that it might break later is the "flexible arm" which is not that flexible and I'm afraid it might lose its plasticity over time.

For now, it works fine, screws and unscrews quickly, the phone doesn't move when you attach it, and the "flexible arm" stays in place when you twist it where you want. It doesn't hold a tablet, or if it does, it has to be super thin (phone thickness) and I don't know if it can withstand the weight in the long run.

I might get a second one because another similar thing I bought for phones turned out to be useless.

The tablet does not fit, only the mobile phone fits. It does not open to accommodate a tablet or anything larger. As for its complexity, I have no words. You have to place it above your head in a space, otherwise the sides cannot hold the weight of the mobile phone and you are forced to hold them with both hands or one occasionally. It's a waste of money. It was bought for a tablet, not for a mobile phone, whatever that means. It is absolutely not suitable for a tablet, for a mobile phone something happens, but again you have to place it on your head or in a space that you have or I don't know, some shelf above the bed or wherever else you want in order for it to hold it differently. There is no chance it will stay upright.

I upgraded from a simple Chinese one that cost 3€. It's worth every penny. Good construction, stable, convenient rotation (3 points), and in the right color. It's important not to have a black arm above your head.

Always depends on the money evaluation. Very stable with many options, goes quite high and quite far. As a negative, I will only say that the clamp it has for the device is spring-loaded, which means that with hasty use, the device may possibly fall, etc. but with a little attention, it is flawless
