I purchased this slow cooker one month ago and have used it several times. It is by far the best slow cooker I have owned. The 3.5 is the perfect size for the 2 of us, plus left overs. The function that sold me this cooker it has 4 heat settings - simmer, low, high and warm. Ease of Cleaning removal crock is very easy to clean Design Stainless Steel exterior matches my kitchen Durability I have only had it a month but have no reson to believe it will last a while.
