Example Input: Got this beautiful light box as a gift for my friend and she absolutely loves it, goes perfectly with her room and she was so happy to receive this as a gift. Makes her room great and adds so much style.
Example Output: positive

Example Input: First of all, they took a long time to get to me. They come with no instructions. No way of knowing when they are fully charged. Charge doesn't last long, at all. And they scratch very easily. Very disappointed with this product unfortunately.
Example Output: negative

Example Input: Are those real bluetooth ? I just received one and I have to plug in to my phone in order to connect bluetooth. if it has bluetooth connection, why I have to plug it in to my phone all the time to stay connect? If I have to plug it in to my phone, what is different from regular earphone? As there is no Q & A to ask a question to the seller, i have to put a equation here. To Seller: can you response my question ASAP?
Example Output:
negative
