I have 2 of these I think they are great you can open them with 1hand and are so easy to fix to the wall or door. They might be simple but children find these hard to open. They also fix to doors and walls for wheelchair access which is good as so many don't and it's great value for money.
What made me get this gate was that it didn't have a bar to trip over which is what is do on a regular basis....not vary safe for the top of stairs and while holding a baby or while pregnant! It was easy to install and easy to use, the kids can not move it even the slightest due to wall mounting....they were able to move the pressure fitted ones too easily....and because it has to be lifted to open even the older son can't open it.
