I used it for about 2 months, but I started letting my dog run free in the room, so I no longer need it and am putting it up for sale. There are a few bite marks only on the bottom of the opening. Other than that, it's in good condition. I used it for a Toy Poodle puppy. Bolts and the hex wrench for tightening are also included. I will disassemble it and wrap it in bubble wrap for shipping.
