I connected it once, but then I never used it again, and the return period has long passed, so I'm putting it up for sale. It's barely been used, so it works perfectly! *Please note that there are no instructions or box. The cable in the 7th image was also bought but never used. I was thinking of throwing it away, so I'll include the cable in the image as a bonus.
