I have one, love it. Changed my sleep patterns, and, most importantly, I'm able to get by on 5 1/2 - 6 1/2 hours of sleep without waking up groggy.<p>Prior to MyZeo, if I wanted to wake up refreshed, and relaxed, without any effort, I'd have to get about 7 1/2 hours of sleep and let the sunlight coming in my window wake me up. But, I knew from experience, that depending on how I woke up - I could go for quite a while with about 6 hours of sleep and feel fine all day without that morning struggle to break through that "inertia."<p>That's the cool part of myZeo - you basically say "Here is a window when I want you to wake me up, but make sure I'm _just_ exiting REM sleep, so i'll wake up refreshed!"<p>For those that doubt the value of the device, ask yourself what you would pay to :<p><pre><code> A) Get back one hour each day (presuming you are
okay getting 6 1/2 hours of sleep a night
B) Exit sleep refreshed.</code></pre>
