1. The material is good, very textured and exquisite. It is genuine and the manufacturer has a product patent certificate. 2. Easy to use: It uses a special piece of glue to stick to the back of the mobile phone. It can be stuck and removed. It can also be folded and placed directly in the bag without getting in the way. 3. Because the film is attached to the back cover of the mobile phone, it has the function of buffering and preventing falls. 4. When answering calls or playing with mobile phones in public places such as the subway, you can hold it with your fingers. It has a certain anti-robbery function. 5. You can read news headlines when going to the toilet. Hold it and watch it, so you don’t have to worry. You dropped your phone in the toilet! (I have dropped it before) 6. Another function is to use it directly as a stand to watch movies on your mobile phone, which is easy and stable. This is the most powerful thing. 7. The only shortcoming I feel at present is that the adhesive force of the film is too strong, and it is difficult to take it off occasionally (I am a girl after all!). Later, I consulted the manufacturer’s customer service and said that the adhesive force is about 5 kilograms. In order to effectively protect the phone from falling, the customer service provided me with instructions on how to remove it, and the customer service attitude was very good.
