I was considering getting one, but it fails our criteria for an advertised use: yogurt.
It only has a number of fixed temperature settings, and cannot be adjusted to any arbitrary temp. What it thinks is the yogurt range is too low for the cultures we use.
If anyone know of a slow cooker / pasteurizer / yogurt cooker with continuously variable set temp, and ±4°F regulation, let me know. It doesn't also have to be a pressure cooker, but does need to be not just for yogurt, and in particular we want one medium to large vessel, and not a heater for a bunch of jars.
