No instructions
Color: Gold texture
It looks nice and might work well butt there’s no instructions with it. I have a lot of crap going on in my life right now and have had no time to google how to connect this with my computer. Why no instructions????

Good quality
The only thing that I would improve is that when it is open it holds in the back with magnets. So it doesn’t separates from the back
