The Zeo Personal Sleep Coach provided me with the information and tools to make lifestyle changes that were necessary to get a good nights sleep. I was already a pretty good sleeper before I bought the Zeo, but now I'm able to see correlations between activities in my life and my quality of sleep. SmartWake is also great. It keeps me from feeling groggy in the morning by waking me at a natural waking point. The company is also super informative and very helpful. From what I've seen, they have a very dedicated staff that truly cares about their product. If you want to know more about how you sleep, and you're looking to improve your quality of sleep, then the Zeo won't disappoint.
