In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: 4 times now I tried to order this DVD--twice from elsewhere, twice now via Amazon, and ALL times I was sent Blu-ray even though I ordered DVD! The DVD is listed separately from blu-ray: the boxes are different, so I zoomed the photo claiming the "DVD" format, ordered clearly under the "DVD", and under the lower DVD pricing, as Blu-rays are sold at a higher price. Each time I am sent the Blu-ray!!!! I am so frustrated at this terrible advertising! Why is the photo/descrption/price for DVD offered online if only Blu-ray is available? Blu-ray doe NOT work on my DVD player and just want what is clearly marked as offered!
Example Output: negative

Example Input: I have read all reviews before I bought this, luckily, I received an item with any issue. The stun gun can make loud noisy like other buyers said, the flashlight is not bright enough, but It can blind the attacker. I have try the stun function and my friend said it make a huge painful sense.
Example Output: positive

Example Input: I was skeptical of this safe because of some bad reviews. However this is one of my favorite purchases. Everything works perfectly for several months thus far. The video of the guy easily breaking into the safe is a bit misleading; however there is an access "key slot" under the Stanley plate. If you're that worried about someone breaking in I suggest a bigger safe and a change of location haha. I added two motion sensor lights to the inside which really makes a huge difference. The door had a little play in it when closed, a thin foam tape fixed that. I also read a review about finger print issues; if you dont reset the safe before entering prints then any print will work, says so in the manual. Do a proper setup and it works great. If your worried about speed of access I suggest logging your middle finger as well, you can then hit the key and read your print in one motion thia is also much more comfortable. Another thing is log your finger in several positions for easy access. Somehow I was able to disable the open door alarm which I was happy about. I intend to mount this inside a large gun safe so the fact that it is not fireproof is less of an issue to me otherwise that would be the only downside. Highly recommend this safe.
Example Output:
positive
