I love my modius! I use it daily and have for over a year. It is a great ritual to my day. I think it helps me sleep, helps with sugar cravings, and gives me more energy. It will not magically make you lose weight like some expected. The App is difficult to use and crashes regularly. I frequently have trouble getting my modius to pair with my phone. I also suffered terribly with motion sickness at first, but it subsided after a few months of use. Those are my only complaints, it is a great device.
