[EX A]: negative

[EX Q]: I haven't used these products yet, the raincoat used before was very heavy. It's very inconvenient to put on. So I tried this raincoat, it feels great to put on. There is no sense of obstructing action. When I opened the package, I found a variety of raincoats in different colors, each of us can choose the color we like. I think we can take it with us on the field trip. Because it was raining hard days ago, it was I who carried a raincoat like this I won't get caught in the rain, I don't even feel it. It's a great feeling. A raincoat is long enough, it won't get your knees wet. That's not what other raincoats can do. So I suggest you take a raincoat like this. It won't take up your space and it will bring you convenience.
[EX A]: positive

[EX Q]: I have to laugh just to keep from cussing and crying, it says extra small I wasn’t expecting Barbie doll small. This is barley a mustache comb and definitely not a beard comb. It’s smaller than my thumb. Save your money and your time unless you collect dolls or something.
