Question: 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.

Answer: positive

Question: It's a really pretty cover and the fact that they showed what each color phone looked like under the design really helped me choose the perfect cover. It's textured on back, so it helps grip the phone and I'm very pleased with it.

Answer: positive

Question: Gave less than 10 of these treats to my 15 week old puppy, and she had diarrhea for a day and a half. We had to change her normal food just to get her to have solid poops again. I would double check the ingredients with your vet before use because it's safe to say we have stopped feeding her these. I was really excited to try these treats as they weren't too high in calorie compared to other training treats. The package came as pictured, but the treats were bigger than I thought they'd be. They smelled tasty and flavorful, so I'm sad they didn't work out for our girl.

Answer:
negative
