Instruct: Classify Amazon reviews into positive or negative sentiment
Query: flammable and hazardous

If you try to return the item, you get this message:"For safety reasons, items that are classified as hazardous materials or use flammable liquids or gases cannot be returned to Amazon.com."(I have no reason to return it, just thought it to be strange)I keep it on the dashboard of my motorcycle and it works great. Just make sure it's kept flat for it to work properly.
