[EX Q]: I have used this for my terrible joint pain from being on accutane. It has helped me so much! I have also used it on my husbands back for all the pain that he always has and he found relief from it too! So excited I found this.
[EX A]: positive

[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]: Just what i was looking for. At first i had my doubts about these headphones before buying them, but after receiving them, i’m really satisfied! The speaker quality is amazing, and so is the sound quality in the earbuds. It’s comfortable, it sounds great on calls. It’s great overall and really makes my life at work easier. No tangles or anything, i’m able to move and go throughout my day listening to music or chatting.
