I have to say we have been blessed with luck over the crate. Pickle went in first night at 10pm and he woke us at 7.15 next morning when the heating went on. He seems to have a remarkable ability to hold it in. Most weekends we wake first around 8 ish and one Saturday we overslept til 9 and no noise from him whatsoever. He has never messed in the crate. I usually leave a small amount of water at night which is still there in the morning. So all in all the crate has been amazing. Not so the car crate however which he HATES so I need to get a harness to fit onto the seat belt as he's much happier when he is on the seat next to someone!
