I stopped my testing of it due to it being somewhat uncomfortable to wear while sleeping. (that is, it sometimes made my head sore when I woke up) I was able to get it detecting rem sleep once or twice (I think), but the device wasn't really built for sleeping so I switched to more traditional timer-based systems.
Hi, I saw your post about the muse headband a few years ago. I would like to know how that is going. Thanks a lot! Jose
