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

Opened the box, unrolled the mattress, plugged in the motor and then... the motor made a few feeble noises and shut off in less than three seconds. Plugged it into several different outlets with the same results.Intex customer service told me that there are NO WARRANTIES on their air mattresses and the only option was to return it to Amazon for a refund. I will not be ordering any products from Intex in the future.
Output:
Negative
