I contacted Adonit shortly before christmas. They were very helpful and I received a replacement with very little questions asked. They even refunded the shipping costs to Taiwan. Very good and friendly customer service. The new stylus works better than the one before, until now I had no unexpected disconnects. I mainly asked for a refund because my stylus was eating batteries like crazy. The first battery in the replacement lasted for three days, the second one now lasts for more than one week (with 2-6 hrs of daily use). I suspect that the pen pulls energy from the battery even if it is off, so I took the habit of removing the battery when I finish note taking for the day. I gave up early on using Penultimate, because it is not very responsive, wrist protection works only partly but mainly because it syncs always complete notebooks to Evernote. I would prefer that notes taken on separate days were uploaded as separate notes in Evernote. I am quite satisfied with the new Jot Script. I would appreciate if the user could set the period until the pen goes to sleep, but otherwise it is the best stylus I used until now.
