She has reviews of Instant Pots, how to use them and recipes. I now make all of my own yogurt using this recipe:

The one thing I have found is that many recipes do not include the time needed to bring the pot up to pressure, so you do need to add that to over all time.
It is wonderful for soup stock and tough cuts of meats. Many meats can be cooked from frozen. Like many new appliances there is a learning curve and you can convert your current recipes to the Instant Pot. You just need to make sure there is liquid to create the steam, so it comes under pressure.
