It works with the Samsung Galaxy 10.1 2014 Edition. Of course, its' easier to hold than the s-Pen, as you'd expect.
There's a slight offset between where the nib touches the screen and where the ink appears - about 0.5-1mm, I think. You don't get that with the s-pen. However, as long as you don't have to pay too murk for it, its definitely work having.
