Open And Identify
Using screwdriver and adhesive remover to open it.
What impressed me a lot
This product is much more simple than I thought before, which only includes 3 parts to achieve the functions. They reduce all the extra stuffs to make it easier and cheaper.
As we noticed in the video, they use physical button to generate the power which triggered by the slide button on the cover. And they only gave a tiny led unit compacted in the board as indicator light.
The Cost Control, CUNNING.
