[EX Q]: I liked reading the true relationship between two troubled teens. There could have been more details given on each situation. The book was somewhat sad throughout as well.
[EX A]: Good Review

[EX Q]: It is the perfect size for a small space, which is where ours is. The problem I have with it... right out of box it only worked once. When plugged in and turned on, there was not noise or light, just NO power to unit. After 3 days all lights come on so it's ok, but who cares when one has no power!
[EX A]: Bad review

[EX Q]: This heater works really well. You set temp's to desired amount of temperature,its a lot like a big space heater. It will blow cold air into room very quickly.
[EX A]:
Good Review
