I give four points, because I think that the thing is useful if you do not WITH A SURFACE OF THE FIRST GENERATION USED! That's what I had before, however, and in the offer is nowhere that it works only with Surface Pro. I've looked through all of the different adapter offerings offered on Amazon - and all the others had been in the headline "Surface Pro". Therefore, a point deduction. After all, one gets from Deltatec a return label. But the action was unnecessary for me after all.
