Works fine now but when I contacted 24/7 support they told me they were unavailable. I assume that the 24 hours are not consecutive. I've since bought a new one from Microsoft so I can compare the sites. In short, both work pretty much the same. Sometimes I prefer to have two buttons next to each other, sometimes I prefer the eraser tip feel of the original. I think I like being able to swap out the battery for a rechargeable one, but from what I've heard none of these pens will survive a rechargeable battery.
