I have had it for 1.5 years, just like my cat. The cat is 2 years old. I never had any issues with transporting it. Even on a plane, everything went smoothly and perfectly. It has never presented any general problems to me. I don't transport it so much with the cage as it is constantly at home, but for distances like from the garage to the house and from the house to the vet, there has never been an issue.

It is the worst of all... it does not hold the weight it claims, resulting in the door falling as soon as the cat enters.

Unreliable and dangerous. Poor quality thin soft plastic resulting in easy distortion and door detachment.
