How could people be so dumb when it comes to South America? Argentina is not the only country that has fluoride in the water; almost all the countries here have it, including Brazil for over 15 years. I'm a dentist and I know what I'm talking about. Please, if you want to talk about us you should study the subject first. Is this product review negative?

input:  Now, answer this question: Title: Couldn't get through it Review: I too had heard an interview with the author and thought it would be very interesting to hear his story. Although many callers on the radio interview with the author were in disbelief of his stories, I believed him and was interested to hear a story of undercover work that was non-fiction. But after reading half the book I could not go further because it seemed to fictional to me. Kind of like a James Bond movie - if that's what you want, then you'll be satisfied. If you want believeble, you won't get it here in my opinion. Is this product review negative?

input:  Now, answer this question: Title: Can be used plugged in Review: I just bought this item after reading other reviews and wanted to add information I was looking for at the time. I was concerned about it only staying warm for an hour - most parties last longer than that. I was pleased to read in the directions that this can be safely used plugged in over an extended period of time. The unit cycles itself on and off to maintain the proper temperature. It also can safely be used with a proper extension cord. Three 11X7 glass dishes fit on it with room to spare. Two llx7 and one 9x13 fits, but more snugly. The unit itself is very heavy. I have model TWT-40 and the cord does come off. Hope this info helps! Only reason I am not giving it five stars is because I have not actually used it for a meal, but I have had it plugged in and it got hot quickly. I see no reason why it won't be perfect for large gatherings and family get-togethers. Is this product review negative?
