I have got 2 Tower slow cookers and my daughter took one with her to uni - thats how easy they are to use ! You just plug it in and can leave it on for hours and come home to a lovely meal waiting for you. It works for us as I work til 8 some nights so my family can eat as soon as they get in without waiting for me if they want to. Its very easy to use and I wouldnt be without it. Another time was when I did a buffet spread for a party and used it for chilli and the other for a bouef bourgignon - it kept it hot all evening. I thoroughly recommend them and they are economical to use too.
