We are improving the App UI design, we keep upgrading the App for that. Currently, labels for our sample batch are not very appealing and we do not offer screws for Sonoff, 
we will surely improve all these issues for our final product. Many people care about CE certification very much, we will also work on it. Another thing that most people worry about is the server. 
We use Amazon AWS Global Server, which is stable and easy to be accessed. We have a team to back up our smart home products and we'll make them better and better.
