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.

Let me give you an example: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
The answer to this example can be: negative
Here is why: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

OK. solve this:
Overview: The speaker is very well built and portable. The build is excellent, made out of very strong plastic. The speaker has good insulation from dust and water, providing some needed features that other high end speakers don't have. Build: In my testing the speaker held out really well. I took it to camp to test out the durability. This speaker held out really well. The front amps get very loud when paired by Bluetooth. In my case I used an iPhone XS. In my case i used the speaker while I was outside By the campfire. Battery: I tested the battery nonstop and noticed that I got easily 6-8 hours on constant use. In my defense my phone didn't last as long thus battery life is very subjective to the loudness and if Bluetooth is use. I mostly connected the device via Bluetooth. Features: The main features that this speaker has are the micro sd card slot, and microphone built in. I used the speaker for offline use by transmitting music via bluetooth. Because I was camping the service in my area was fairly poor, thus just adding my whole music library to the micro sd or usb is very convenient.
Answer:
positive
