Slow cookers have come along way from when i had one which i still use,i only had high and lo settings,which still took quite a while to cook,there are so many sizes for one a family and a tribe,but i find some totally make meat dissolve,and so pressure cookers have come along way since i was given one as a wedding present and the buggar frightened the life out of me till i realised it wouldnt blow up,now they are just quick,retain all the vitamins,are silent,if you want your food cooked quickly then pressure cooker and if you can wait and let it slow cook and apparently energy saving chose a slow cooker!!!
