We have one to keep little people out of the kitchen when the oven's on. (Dh: 'It pisses our dwarf friends off')
Never witnessed a running into incident, and to be honest, if it was at the top of a staircase I might be wary. The catch is complicated enough to keep unsuspecting adults at bay too. So if you regularly have visitors needing to go through it you could get a bit fed up with having to open the gate for them. That said, most stairgates are unfathomable first time IME.
Have had quite a few appreciative comments about ours, and I like it. Kiddicare def the cheapest place to get one too. (Brand new that is)
i have this gate at the top of the stairs and my ds tries to climb it / run at it/ crawl under and is unable to dp all of them. It is marvellous cos it rolls back and the opening mechanism is a little sticky so too much for little hands to be able to work out.
I would recommed one of these personally
We have one (actually have another 2 in the garage we didn't fit) and I really dislike them. I still find them very difficult to open and close and visitors really have no hope. My 3 year old can get through our "normal" gates (which is great for his freedom while putting up with his younger brother).
All that said, if you do decide to go for them, send me a CAT as I have two unopened ones - can do you a deal on them
