Great product; very effective noise reduction
This is the premiere of sound machines.  Creates very loud (if desired) yet pleasant white noise.  Started out using in the baby's room, and now it is also a mainstay on all our trips.  It is really great for hotels or cramped quarters with relatives/friends!  We recently used on a trip with our friends; their toddler and dogs were one room over with very thin walls.  Nothing woke us the whole night thanks to this sound machine.  It's a little pricier than others out there but worth it for the quality.  I have baby #2 on the way and have purchased a second unit for his bedroom.
