I to am experiencing that it gives new meaning to "slow."
For example, when cooked in our 6 Quart Crock pot pork chops are done in 6 hours on low, with the new 4 Quart Crock pot it has taken approximately 9 hours on high and they are just getting to the tender point. Setting it on 3 more hours doesn't do much better. Our old 6 qt one that does a much better job.
