Wonderful Way to Wake Up - If You Must
on June 29, 2011
These were originally giveaways from Master Card and I greatly regret I did not buy them in bulk. I have not used it for white noise so I can't comment on battery life for that purpose. The batteries last at least a year when using it as an alarm clock only. The machines tend to die after 5 years or so, but they are ideal in the meantime.
The choices of sounds (I like the gong or the bird) and the volume control make it ideal for someone who does not want to be blasted out of bed by the over-the-top siren sounds that some clocks have.
