I have recently upgraded from a very old CB-2000 to a metal cage. At first thought I thought the weight would be an issue but for the last month have found it to be extremely comfortable- I like the open concept with a large hole to pee with thereby removing the “spray” or mess associated with smaller holes. The open concept allows for easy cleaning and only wish would be for the cage to be a little shorter - when I upgrade to a custome fit I will make that change. the wife is on board and currently holds the key and enjoys teasing. if anyone is interested where I got this cage, let me know. take care and wish everyone the very best
