I used this to cook a pork roast. It is the perfect size and I able to include everything we wanted in with our roast to feed a family of 6 (5 adults, 1 toddler). I put it on roast for only an hour and it almost fully cooked it but I wanted to wait to eat, so I put it on low for another hour. We even waited about 3 hours after and it was on warm during that time. It turned out perfectly. All the vegetables were soft and the meat was fully cooked and juicy. 

After cooking, it was easy to clean up. Nothing stuck to it and I was able to wash it with ease. 

Overall, I love it and can't wait to use the other settings. I love having multiple ways to cook and it's going to be used quite often. I love that it comes with it's own rice cooker as well. And the vent hole is large enough to stick a meat thermometer in without having to take the lid off. I'd highly recommend this to anyone.
