Example Input: Only looks good in the picture, and the materials are very rough, stained and cheap. The copper is a lining not pure. I should've know due to low price but even at the price it is definitely very poor workmanship and not worthwhile. Now I have spend more money getting something better so as they say; better to spend wisely then hunt for bargains.
Example Output: negative

Example Input: I bought this to test it out since I needed to buy several solar lights. The detachable solar panel was a huge plus. I left this out sitting along with another unit from a separate company for a few months I got busy/forgot these were out there. Well I went out today to install it and this unit is dead. I popped the battery compartment no seal in the lid. one of the batteries corroded. So Im going to see if I can bring it back to life with a little cleaning. for now 1 star because it died after a few months of rain.
Example Output: negative

Example Input: I am very pleased with this purchase. I bought it because I have a bamboo type a luggage rack in the same room and it really adds to the Casablanca type atmosphere. Would buy again.
Example Output:
positive
