This was the telescopic controller. It was really good quality but because of the lack of good tablet options that would fit, I ended up just returning it.
I replaced it with a £10 xbox controller clip from the same company which I modified to work with tablets. I designed and 3d printed a magnetic clip holder so I could use it with my old 2048 x 1536 resolution mini tablet. It works a treat for local and cloud streaming around the house and in bed.
