Well I got the newer pen (the one with no clip and one long oval button). It worked for a while. THen today, I brought it out and it doesn't work again. It may be the battery. I wished there was a battery indicator somewhere. What I'm finding is that I can't depend on this thing. If I go into an important meeting, I can't rely on this thing to work 100%. So rather than bringing my SurfaceBook, I bring a regular notepad. It's a shame. This BT technology is not 100% reliable. The pen with battery should last 6 months...not 1 month. They still haven't perfected this yet. Someday I hope get their SH_T together and make a pen that just works...just like the WACOM pens on my Samsung Notes.
