All I know is, I bought one, and less than a week later, I was extremely frustrated and had to order a new model to keep pace with any significant cravings. And I've seen numerous people post almost exactly the same story. You're right to some extent: I have heard from people who have been quite satisfied with it, and I'm not saying that it's a "bad"
device. I'm just saying that when, in my experiences, dissatisfied customers seem to outnumber satisfied customers maybe 10:1, well... I'm certainly going to point out that fact and give my frank assessment of it. I feel that if I had heard more about it before I ever ordered mine, maybe I could have saved myself $60.
