Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Input: Consider Input: Adapter worked flawlessly for six months, then became intermittent. Seems to be broken or shorted somewhere near the connector to the computer. Even the ridiculously flimsy cord from Apple lasted longer than six months, so I can't say I'm pleased. Macally says they'll sell the connector cable separately for $17.00 which is not much of a bargain.

Output: Negative

Input: Consider Input: What a junk. Every time NOMAD thinks the file is corrupt the OS freezes. The only way to recover is to plug the power cord and go into recovery mode. So if you happen to be out of the house and you have a frozen OS you can't use NOMAD until you get home. After OS froze twice on me in the subway I returned the jukebox.

Output: Negative

Input: Consider Input: This is the first time I buy a product from this provider and I will never do it again, they sold me a charger without a box and that looks kind of used, when I try to charge my batteries they never did it. After a couple tries I went to a local dealer and got a brand new that made a great job in a couple hours.
Output: Negative
