My favorite feature of this cooker is being able to brown in the pot then add the remaining ingredients.  No need to brown on the stove first.  My second favorite is being able to set the time and cooking level then it automatically goes into warm.  No more over cooking as with the last four cookers I've owned.  It may be a bit pricey but well worth it if you use your cooker as often as I use mine...weekly.  I bought the four and six quart sizes.
