[EX Q]: this DeLonghi DFH550R heater is an extremely poor product and the customer service is non-existent,doesn't have a physical address or phone number and never gives their names...buyer beware...read their absolutely ridiculous return policy before buying...if you open any package they won't take it back...if you write a truthful negative feedback, they'll be after you like " ticks on a hound " !!!
[EX A]: Negative

[EX Q]: This would have been a very short book if all of the racism and sexuality were to be removed. I read it for an Appalachian Literature class, and I felt this book was so racey that I couldn't enjoy reading it. The vulgarity in it is also not necessary, and I feel that it should not be called literature because of this.
[EX A]: Negative

[EX Q]: Behind the Eyes is slightly different from Amy's two previous releases; BTE is more mature and it gets better and better the more one listens to it. "Turn This World Around" is my favorite on the CD, but the rest of the material is also great.
[EX A]:
Positive
