I LOVE this! I have only had it about a week now, but have used it 5 times, I bought the snazzy red version. =) It is so easy to use, just pour the ingredients in and let the machine do the churning. No rock salt or ice required. It is very much worth the investment to me because it will be healthier(not to mention preservative free) and cheaper than store-bought ice cream, PLUS I can put anything in that I want to! It makes ice cream, smoothies, sherbet, margaritas.....just about anything that is a frozen liquid. Off to make my strawberry ice cream now!!!
