Today I two of the safety gate installed (each with 7cm extension which I bought separately on Amazon), take this for my dog: relatively easy (even without drilling in my case) installed, very good quality, holds "bomb-proof". These safety gates are in my opinion worth every penny! I can not imagine what you here me - at least for my purposes - could still be improved (experience with young children, I can not judge in this regard), to order the same to me even as a "thing". In short: Quite excellent, I'm really really excited! And that's saying something with me ... ;-)
