Excellent product, worthy of its name.
Sturdy construction with a good magnet, it hasn't bothered me at all.
Just needs a smooth surface to press on and you're good to go. It doesn't go anywhere. The 3M adhesive is so strong that I pulled it for fun to check and it detached the vent of the Golf (for those who know, right above the button, between the air vents).
Make sure you are certain about where you want to place it!

Very convenient base if there is a smooth surface to place it. Discreet in size and stable in terms of how it holds the phone. However, a major drawback is that the tape peels off with the heat in the summer.

You get what you pay for.

The base stuck immediately to the dashboard of the car (Mercedes A180). I left it for 24 hours for the glue to set, then I placed the provided metal plate between my phone case and the phone, and it sticks very comfortably.

It doesn't move in potholes and it is easily adjustable in terms of orientation.

When I remove the phone, the base itself is small and very discreet.

My phone is relatively heavy, 190 grams, and the case is a hard Spigen.

No suction cup, no huge mechanism to hold the phone, nothing.

Highly recommended!

Very stable and rotates degrees (turns) accordingly, meaning it adjusts to how you prefer to place your mobile phone each time

It sticks very well to the car dashboard, even though it is not completely flat (the dashboard..).
The package includes two adhesive magnets, one large and one small. Both are very stable and easy to remove if needed.
I would have liked it to have a slightly longer arm to accommodate tablets and larger phones when they are in an upright position.

It is expensive... it sticks with adhesive so you cannot change its position... it has a screw to change the position on the phone, but it is not stable. No matter how tight you tighten it, it moves, causing the phone to change position while driving. Definitely not worth its price.
