Size - You can easily fit a joint / whole chicken in this slow cooker. There are only two of us and it's probably a bit big for our needs but would be excellent for a family.
Settings - There are 3 settings, low, medium and high. A lot of slow cooker books recommend starting the cooker on high. That is definitely not needed with this slow cooker as low is a bit, well, high!
Cooking time - A lot of reviewers have criticised the cooking time / thermostat but I don't have a problem with it and never 'crozzle' anything. Yes, if you turn the slow cooker on before you leave the house in the morning and don't eat until say 7pm then the contents will be crozzled. However, I bought a timer plug for mine. I set it to come on on low at around Midday and everything is cooked perfectly by the time I get home from work. I also find that the over eager thermostat can sometimes be a benefit....I've put mine on high at around 3pm for a couple of hours and then low for a couple of hours and again, everything is cooked to perfection.
