We have long been looking for a guard that is not to stall, because our old terminal grid has rubbed off the wallpaper right and left, because it was no longer safe to use terminals to 6 years. We have not been disappointed. The grille is tight, as it shall be affixed before the opening, so it can quietly throwing a child on the other hand, the grid is maintained. The grid lies on the ground, so that when it is opened, remains open, so it does not fall by themselves. This is useful in everyday life, if one wants to carry laundry baskets etc. one needs no hand to stop the grid, but you have to of course, always close behind. If the grid is not fully engaged, then it can unfortunately also open a crawling child, so you have to educate yourself and the big kids to the grid really always shut correctly and not just to sit or to let half snap. This grid is for our 4 year old but also very easy to use, press a button and then lifts you the grille slightly and put it on; Close to it is drawn and a little raised and pushed into the socket. I suppose that a clever two year old child will also get open the grille. But until then it should already can walk stairs. Cleverly, I also think that the child's finger during use can not be trapped, for example if the child is ready and up to the stairs coming up from the bottom and the grid then opens and closes, even though the child clings to the grid. The material is wood with plastic elements, very nice to look at, goes well with our furniture. Pitching really have to look at the manual, because it is not self-explanatory, if you the parts has before him. All in all a great purchase, the grid is really worth the money.
