Worth the bit of extra money!!
This is significantly better than any recorded white noise that I've ever found.  This product actually pushes air, instead of just playing a recorded noise, and it works perfectly for someone who needs noise to study/work/sleep/etc.<br /><br />If you are looking for your sound machine to multitask, i.e. also be an alarm clock, this is not for you, but I would purchase this and an additional alarm clock because it's that good!
