I purchased this at an electronics store when I bought my Surface PC. I mainly used it as a PC accessory, so I rarely used it and ended up storing it away. Since I bought an iPad, I no longer have a need for it, so I hope to pass it on to someone who is looking for one. I believe it's no longer sold on the official website. *I haven't checked the functionality at the time of listing, so I will confirm it if someone expresses interest.*
