I bought to put in front of my glass walled gas fireplace, to prevent people/kids from accidentally touching the hot glass and burning themselves. This allows the hot air to pass through and is stable enough I am not worried about kids accidentally bumping into the glass. It is steady if someone presses into it, but a kid could potentially move it from its place.
I like the minimal design and that the screen barely obstructs the view of the fire. You can slightly see the screen but nothing major. I previously had a glass screen but the glass got too warm and blocked the heat going into the room. This is the perfect compromise of function and visibility.
