This is a wonderful product. To start with, it's small and unobtrusive. You can use it at home, the office, or even take it traveling with its compact size. It's great that you don't have to leave it plugged in. There are directions with it, however, it is also very easy to figure out as all of the buttons are well-marked. There are 36 different options for sounds so it's easy to find something that will be relaxing. And having multiple options for a timer is great as well. This is a great little machine and I would recommend it to others.
