Question: Ordered size small in blue. I'm about 5'8, 150 lbs with more of an athletic build. This dress fits perfectly. The color is more vibrant than I thought it would be but I love it. Fabric is pretty good quality and there is a little stretch in it, but very comfortable. Very happy with this purchase.

Answer: positive

Question: I was taking this supplement to help me sleep. They were effective once I started taking two capsules just after supper. However, I did not sleep through the night. I am still trying different supplements

Answer: positive

Question: I bought this product for my Iphone to be able to charge my phone and use my headphones at the same time. I plugged my headphones up and they do not work when I facetime at all, I thought maybe I had a defective product so I ordered a new one and it does the exact same thing. It also charges very slow. Clearly this product does not serve its purpose.

Answer:
negative
