You are an excellent writer but I need to tell you something as follows:
Each article should have its own emphasis but yours do not have.You should emphasize on discussing one or several important functions , its benifit and what problems it can solove.
You should write in the consumers' point of view and consider what kind of products the consumers want to buy and what they would think of the products, which are in fact attractive to the readers.
Can you edit the two articles of them ?Please show your real write level so I can give you other projects in the future.
