Difficult to assemble, unstable
Positive: Easy to adjust to the sides so it fits the width of the car.
Negative: Extremely difficult to mount securely. The feet come off easily while you’re trying to push the whole barrier firmly up to the ceiling to create tension. Then the other side you’re not working on becomes loose. The whole thing is a hassle. Since the barrier goes straight up and down from floor to ceiling, it’s easy for the dog to bump into the lower part, which can make the whole barrier topple over onto the dog, which is stressful.
