Affordable, easy to use, very useful as a light door stop; it is installed easily and quickly as long as someone has at least basic technical knowledge and the proper tools.

It needs to be screwed both to the floor and to the door, which is a deterrent for some who do not want to drill into the door and the floor.
In the case of very strong wind, the magnet does not hold the door and it closes, which is a negative for residents of windy areas.
The sound of the door being released from the magnet in a quiet environment is noticeable, a negative for those who have small children and patients.
I cannot have an opinion on the product's behavior on a heavy door because I do not have one where I installed the stops.

I put it to stop the heavy courtyard door. I didn't expect much.
When it's not windy, it does its job, but it can't hold it with air.
When it's wet, the tongue sticks in place and doesn't lift to meet the magnet,
you have to use your nail to detach it or wait for it to dry.
There it loses one star.

Perfect product for installing on an interior staircase door to prevent the baby from opening it. I didn't screw it, I used double-sided tape and glued it because I couldn't drill into marble and glass. And of course, I didn't want to create any wounds. It does everything it promises
