I love this little machine. It makes a single serving of granite, sorbet, frozen yogurt, or ice cream in less than 10 minutes.
The only bad thing about it is the paddle, which is terribly fragile. Mine broke the first time I used it. Apparently, this is a known issue, because you can buy replacement paddles quite easily. I think they are a bit expensive - the entire machine cost me $20 (now it's $30) and the replacement paddles are $10 - but I have some ideas for making the paddles less fragile. The second paddle lasted several months. I just ordered another paddle and I'll see if my life-extending ideas for it work.
If it does, then I'll whole-heartedly recommend this device for those who love small frozen treats.
