We have wooden stairs (no carpet) and were afraid for our 2 yr. old grandson. We couldn't let him out of sight for a moment. Since installing the Smart Retract system, we have had much greater peace of mind. The tension is too strong for him to unhook it, even in the "unlock" position. We keep it "locked," however, just to be sure. It was easy to install and is made of quality materials. Worth every penny!
