So you have trouble sleeping at night and getting up in the morning. With this device you can learn to sleep, again, if you’re an insomniac. Just sleep with the sensor band tied to your head, and the electromagnetic data from your brain will get recorded on an SD card. The data can be monitored on a bedside monitor, to help you know what you did right to sleep well. Its alarm is really cool. It can determine the best time to wake you up, the time when your sleep is lightest, so you won’t be groggy. If $400 seems too steep, compare that with going to a sleep therapist.
