I got this about a week ago, and had been enjoying it up until a few minutes ago, when I grabbed it, touched it to the screen, and saw that the tip had just fallen off/out of the end of the barrel. I can't find it anywhere, and this stylus (as far as I can't tell) isn't designed to have replaceable tips, so all I can assume is that the adhesive used to fix the tip isn't strong enough.For the record, I always kept my stylus plugged into the headphone jack on the bottom of my nexus 7 when not in use, and never stuffed it into a small space that might have rubbed it loose.
