[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've been drinking these for years. When they changed the formula, it ADDED SUGAR, tastes WORSE, AND often LEAKS. Totally unacceptable, especially for how expensive these are. I've called Gevalia numerous times to try and explain why then need to go back. Seems EVERYONE liked the old formula better. And it was healthier for you. FAIL!
[EX A]: negative

[EX Q]: One of the brushes on the side was broken off when it arrived. It is made of wood and was split in half along the wood grain. Wood is a great material but just not for this application. It should have been made of nylon or some other composite. I would never recommend this product.
[EX A]:
