I bought this not so long ago and it worked all right, but the only concern I have is that the reusable cubes took forever to freeze. I put them in my freezer for over 15 hours and when I took them out they were cold with little chunks of ice, but not completely frozen. I put them in the slushy cup and poured in a chilled strawberry smoothie because that was the only drink I had at the time. I screwed on the top and shook for about 3.5 minutes. When I open the top I was quite surprised because my strawberry smoothie turned into a thick slushy. It was yummy, healthy, fun, and easy. I was scared to buy it at first because of all of the negative reviews, but I really recommend it.
I purchased one of these for my 11 year old son after he saw it on television. After reading the negative review above, I was hesitant, but I figured I could take it back if it truly didn't work. I warned my son about the review but we decided to try it.
It works great! We froze the cubes for twelve hours, not the 2-3 minimum that they say. The container is a little leaky, but we put a paper towel around it and my son shook away. After less than two minutes he had a slushy. My son was thrilled.
First we tried chocolate milk, then lemonade, then Gatorade. All worked great. So great, that my son urged me to write this review so that other parents would agree to get them for their kids.
I was very excited to get this for my daughter, but very disappointed in the product once we used it. When you shake the container it leaks all over the place if you don't have your finger perfectly over the hole on the top of the lid. The liquid also doesn't really get too slushy as I had hoped. The drink really is more liquid then icy. Super disappointed and would not recommend this product.
