Bests & Worsts Reviews from Amazon

I had been using the original Muse since June and was enjoying the improved state of calm. Then I saw the Muse 2, and their promotional materials that spoke to all new features and data. I figured it would provide better feedback on my meditation practice. Unfortunately, that's not the case. First, the Muse 2 drops connections 2-4+ times during a 30 minute meditation session. Before it drops, it will either give lots of static/rain sound with no change as I focus my attention. Alternatively, it will give the impression that I'm perfectly present with only birds chirping. Reconnecting (Android) takes several attempts. Also, I have left my Muse charging over night but find that the battery indicator in the software shows less than a full charge. The app crashes upon opening about 30-50% of the time. But the biggest annoyance is that all of the additional sensors (heart rate, movement, breathing) can't be used together with the brain sensors. In other words, where I would have expected to see my calm/neutral/active graph with the HR, movement and breathing lines overlaid, that's not how it works. Instead, it appears that only one set of sensors is used at any one time, so you get movement OR heart rate OR breathing OR brain sensing. I wish I hadn't spent the extra money on the Muse 2 and had stuck with my original Muse.
