I got this stair gate and have had to take it apart once already as it has a spring inside to flick the bolt that came off. I fixed it yet the bottom bit still sticks and has to be pulled at times. Linden is owned by nuby I have found out so this explains why it's so rubbish. I complained about the fault and I never saw a reply from them. I have two gates by them both are broken through normal use so I will not be buying from them again.
