Instruct: Classify Amazon reviews into positive or negative sentiment
Query: DON'T ORDER THIS!

There's nothing wrong with the sander. The problem is this ad. It's a bait-and-switch. You won't get the 15 discs, you'll get none. If/When you inquire, you'll eventually get five. If/When you inquire again, you'll be transferred by Amazon to the shipper, who will tell you that Amazon made a mistake and all they agreed to is five discs. That may well be true, but if it is, why is this ad still running? Very disappointing.
