This is a great kitchen tool that works perfectly fine with perfect outcomes. At first, I did not know if I will enjoy using it this much however after couple successful using it, I love it. First of all, it is very convenient. you just need to want it to do it. The frozen stuff can be just placed in to the pot and set up the timer. the system will start running after your set time. the water will start circulate as well as the heating. This makes the water the hot water distributed evenly. Do the meat or what ever you put in the pot will cooked well every part. The material is very good. it is very well design and easy to use it. the control button works perfectly fine. it comes with recipe book. Which very handy. you may increase your repertoire of food. I love it and strongly recommend it.
