Nice product!
I really like the size of this sound machine and the sound and color options are nice.  The only thing that seems to be a problem so far is when travelling, it is easily turned on due to the on/off is a button and not a switch, so when it presses up against anything it turns on.  Also, to chose the sound or color you want, you have to go through all sounds or colors until you get to the one you prefer.  Other than those minor faults, I really like using this for my toddler's nap time.
