I discovered the Slumber Scents machine at Mirbeau Inn and Spa in Plymouth MA. All Mirbeau properties have them! The features are amazing. Blue tooth, USB port, different sounds that aren't annoying after 2 minutes! The color changing is fun. Different brightnesses for the clock and the essential oils diffuser is so nice. Just a few drops of your favorite therapeutic essential oil with cold water and that's it. So easy to use. A perfect gift. This machine helps me go to sleep every night and my husband loves it too.
