It is a round door stop (not particularly heavy) with rubber around it. It is quite small, if you want to squeeze it between the door and the wall get something bigger because the door handle will definitely find the wall again. It has the same logic but bigger and cheaper at a large technical store. It definitely does not justify its price (and I bought two). Very expensive. For the same size you can get 2 for 5€

Very good and stable application. Make sure it is the size you want. I didn't see the dimensions and from the photo I thought it was much bigger :)

Excellent, I will say the same.
Discreet, beautiful in the space, and sturdy.
We stuck it to the floor for the aluminum balcony door (heavy) on the 4th floor with excessive wind, and every time the door slammed, it didn't come off even once and saved the kitchen counter from a strong hit!
With closed eyes for anyone considering it.

Excellent really. You clearly avoid the hole in the floor, I have put it for the front door of the house and it is excellent.
