I read the reviews after I purchased, which is unusual for me. I needed a very specific style of gate for my open plan house, and was making do with old pen parts taped together (Ugh!) My dogs were both terrified of these as they fell over a lot. The younger one, a Coton de Tulèar, liked to push previous gates open.  After a dismal half hour trying to figure out how a thin screw could possibly go into a wider groove and stay there, I discovered the two square end nuts had fallen off and were wedged into the groove when I loosened the screw per instructions. Shaking the gate dislodged them and I was able to put both together in five minutes. The gates both broke shortly after installation.
