PROBLEM: Review: I feel that these are a necessity especially if you live in colder winter climates where you may have the windows closed for a few months.I prefer this model as it plugs in to an outlet rather than battery operated units.I found the models through Amazaon were several dollars cheaper than stores around my area. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: I used the search window using "3-d movies" as the criteria and this movie popped up along with dozens of other 3-d movies, but when I received it, I realized I had not read the description close enough to see that this movie was NOT 3-d. Amazon-please don't place 2-d movies selections in with the 3-d ones! I had to pay $2.98 to return an item that shouldn't have been offered in a search of 3-d movie selections. Ouch. All in all I love Amazon, but I'll be more careful in the future. My bad. 
 Polarity: Positive

SOLUTION: False

PROBLEM: Review: This puzzle is very easy to solve, I would not recommend it for anyone. Buy the "original" "Don't Break the Bottle", it will keep you entertained much longer.

SOLUTION:
True
