I've had this a little over a year and noticed blue stains on the ice in my deep freeze. I thought a Popsicle broke open until I moved this ice cream maker and the blue spot moved with it. I've only used it half a dozen times. I'm really disappointed. My husband gave this to me for Christmas one year because I'm lactose intolerant to cows milk, therefor we use goats milk to make ice cream. It's a great idea, just a poor design somehow. I have yet to find out where it's leaking.
