I have had this white noise sound machine by Big Red Rooster for a couple of weeks now, as it had been delayed by the postal service, but it was very much worth the wait.  The sound is clear and I like that the timer can be set to up to 60 minutes at a time.  The sound machine also included an a/c adapter so it can be plugged into the wall when sitting on your night table.  I like that it also has the option to run on 3 AA batteries as this makes the machine super portable.  Included sounds are: Rain, Brook, Ocean, Thunder, White Noise, and Summer Night.  I put this on the Brook setting, to help calm my dogs from the fireworks on New Years and it helped them a lot.  My personal favorite settings for relaxing are the Ocean and Summer Night, and I would definitely recommend this sound machine to others. [This review was collected as part of a promotion.]
