Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Detailed Observer!

I haven't personally taken this product myself but planned on it. I noticed as I was looking through the reviews that all of the good high rating reviews were published at around the same time. To me, this kind of looks like someone from the supplement company is trying to promote this product by writing bogus reviews under different names or aliases. I've now decided to not buy this product. Personally, my inner belief is telling me that all diet pills are BS. In my case, I'm hypothyroidic and so I'll let the endocrinologists prescribe me real medication. Be aware when looking for diet pills!
