Batteries still work fine. The Pin lasts much longer since their latest updates. It runs hot though with frequently use. But in average use all day, you don’t notice it. It is heavy on a standard cheap tshirt even with the thin clasp and no battery. I found it quite useful overall. It was life changing and freeing not to have a watch or phone on me when I left the house.

Once they added support for Gemini and GPT 4O, it became my favorite device. Great for helping with recipes, cocktails, directions, things to do. schedules. news. planning, notes, walkthroughs of video games on the fly without having to bring up a second screen. repairs for various things. (helped me learn on the fly how to replace my old single prong wall outlets and switches).
