Son can't sleep without it
I bought the single speed for my son, as I have the two speed in my room.  The white noise it creates is PERFECT.  You can adjust the pitch by rotating the outer cover.  We, seriously, travel with our Sound Conditioners.  Nothing does a more efficient job of creating a soothing white noise in order to create the absolutely most perfect sleep conditions.  My daughter is expecting her first child this summer, and I plan on buying her one as well.  Before purchasing, check your local bath and bed superstore.  They have started carrying this, as well, and you can use your 20% off coupon on it!  Sweet dreams!
