Small but mighty
I have 3 sound machines in my house, and I actually like this one the best.  The only caveat I have is that you DO get what you pay for, so does this sound like an actual rainstorm right there in the bedroom? No.  But it doesn't sound too bad either.  I have a Conair SU7 and I can hardly stand to listen to all but one of the "white" noises on it.  I also love that this little egg gets loud: another reviewer found it too loud, but it is perfect for masking the noises that wake up the baby when the rest of the house is still awake.  I put it in the room where I already had the First Years Sounds for Silence machine that gives off a pleasant background noise and masks nothing and the two together make a perfect sleep cocoon cacophony.  I only wish it could plug into the wall.  Running all night and for 2 naps a day I am replacing the (rechargable) batteries about every 10-14 days.
