Input:
This raft arrived quickly and as advertised. Good quality construction. Follow the enclosed directions especially the part about not overinflating.  We had no problems, but the advice about underinflating was true - when the sun warms the air inside it really did expand. Also, it was easier to climb on and off of it if it was a little underinflated in the mid section. Great clear windows, fun on our vacation. A bit heavy due to the quality windows, so adults should carry it to avoid the kids dragging it and scratching the windows.

Options:

B: positive
C: neutral
D: negative
E: very negative
Answer: A: very positive
