Dell warrantied my Dell Venue 11 stylus with no questions asked. My issue was that the battery wouldn't last. They sent me a Rev A02 version which also burns right through a battery. Installed battery, tested (worked), set it aside, and the next day the battery was dead. I didn't let the stylus bump around so the button would get pushed. It sat still without pressure on the button. Is Rev A02 the latest and best version? Should I return this one too? Edit: Now it's not inking regularly. Here's link to: a video of the further problem of the pen not writing consistently. Is this a warranty issue (again) or something else?
