Unfortunately, we realized it too late and learned from the company's returns policy that they are only accepted within 15 days. Without having used it much, it had a problem with the front clip that locks the door. But its biggest issue is that the top and bottom parts open very easily. I had put a small kitten inside to take it to the vet, and as it was bouncing around, it managed to open it and get out. I consider it unreliable and not worth the trouble of buying, even if it is cheap.
