I use the IP a lot, for various reasons. First, I make a lot of things with legumes and whole grains, and it makes short work of many of those. In the summer I use it a lot to avoid all that heat getting into the kitchen from my range. I've put my induction burner (the other heat saver in summer) away, and I'll go back to my range pretty much now, except for when I want to cook something really fast or really slow.
The yogurt maker mode works great! Haven't tried the jiu niang mode yet, but I do have some wine balls somewhere!
I've had it for about 2 1/2 years, and it's $10 cheaper now than when I got it, though they have changed it some.
