This is a Type Cover (keyboard) for Surface Pro. I used it with a Surface Pro 4, but it seems to be compatible with the 3, 4, 5, 6, and 7. Please check the compatibility yourself. It has a 6-pin connector. Model: 1725 It's a Signature model with a suede-like surface. It's probably Ice Blue. All keys and the touchpad were working properly until I removed it. It has some signs of use.
