I’m not much of a cook but I do boil healthy desserts/ tong-sui (red bean, green bean soup) every now and then because I like eating them. I purchased this Panasonic slow cooker from SenHeng electrical appliances store years ago and it has lasted well. My wife uses it to boil healthy soups and herbal drinks .There is an adjustable lever which you can manually adjust the heat from low , to moderate to high and you may also set it to auto. Very easy to use and monitor as it has a see-through glass cover.
