[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

[EX Q]: The book is quite interesting but a bit too descriptive and the pictures were somewhat blurry. Some of these paintings are so beautiful that I wished for more clarity in my mind to see them. All said, it was worth every penny. Would make an excellent gift and conversation piece.
[EX A]: Good Review

[EX Q]: I've been using these batteries for years and never had to replace them. The original are good also. We have a lot of wireless devices in our home so we go through lots of batteries. These are far more durable than any other brands. They're just as described. Great price too. I would certainly purchase again when needed. Thank you.
[EX A]:
