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.

The shell is flimsy and brittle with flaps that don't sit flat and a shape that doesn't sit square. The design relies on single snap-button connections on each side and pop-out hangers for the fabric liner. To much glare for what I needed.
negative

I absolutely like it The brain booster influences well on my alertness and memory. I feel much more clear after half an hour of taking them. I think that they even improve my critical thinking.
positive

Fast shipping, But cheap packaging, lots of bubbles despite following the cleaning and installation instructions. pixelated 3D screen, also appears rainbow like when I use it in the car while wearing my sunglasses. I do not recommend this product.
negative
