I have a shine 3 w brown switches and have other keyboards.
The shine 3 has black paint painted over white clear plastic (for led) which is bad sometimes because the paint will wear out after you use it for a while. Some decent gaming keyboards have double plastic layers. The letter keyboard caps also feel very thin and hollow because of how it was built. Compared to my other keyboards, I find the quality kind of 70% there, but it is a fairly cheap keyboard, and is very good for portable.
