I was really on the fence about this, having used Muse 1 for some time, and it still works fine and I really enjoy using it. Sure Muse 2 looks a lot sleeker, and is a little smaller, but I wasn't sure it offered any more value. Eventually, I took the plunge and ordered it, and am so glad I did. The moment you connect it to your Muse app, you instantly unlock 3 new types of meditations and they really do take things to a whole new level. The breath meditation is calming but the heartbeat meditation which syncs with your heart-rate is.. well.. euphoric. I could do this all day. Iv'e had no issues with connection, and it's a really well designed piece of kit. Glad I upgraded.
