Ex Input:
Ive been looking for a little something xtra. To help me through my workouts. I do orange theory and bootcamp. These have helped me keep going and not feel so sore.

Ex Output:
positive

Ex Input:
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.

Ex Output:
negative

Ex Input:
Perfect for my vehicle storage needs, and no slip bottom makes it a lot easier driving around without it sliding back and forth like my old container. Strongly recommend it.

Ex Output:
positive
