Review on Niubya Foldable Portable Lightweight Platform by Michele Arora

As other reviewers have pointed out these are very fragile and should not be used on dogs over 20lbs if not at all. They are quite steep and slippery and there is no safety lock to keep them from collapsing if a dog is sitting on them. I always had to keep them steady and put my foot on the edge so they wouldn't collapse when my 80lb German Shepherd stepped on them. One day she stepped on it and my hand was in the wrong position and my pinky got caught between the wooden step and the metal railing - it broke in half. I wouldn't recommend them to anyone until they add a safety lock.
