I deduct a point for the damage you have to do to your wall to install this correctly and how you have to give people tutorials on how to use it before leaving your kids in their care - otherwise - great investment! We purchased two of these - one for the top of the stairs and one for the bottom. They have lasted through two dogs and two kids! They can take abuse for sure - (my son hangs from them like a monkey and they have never let go.) Very sturdy and look better than plastic. Durability We have purchased two our selves and had them for about 4 years now - still holding strong and we were given one by a friend who had hers for about 6 years before handing it down and it works great. Ease of Use Easy to use if you know what your doing - I can do it one handed with baby in the other and have time to grab my toddlers hand to go down or up, but it takes some getting use to. Babysitters and family members tend to have a really hard time with them. Easy to install if your husband/partner/you are handy. Safety If installed correctly, they won't go anywhere. We used studs/anchors to make sure they were secure and my kids shake them like they are in jail sometimes to get our attention if they want to be on one side or another and they hold up well.
