We have used this white noise machine in my daughter's room for about 3 years.  We purchased it about 5 years ago but had it in the box as a backup for when her old one failed.  Nonetheless it was used nightly for about 3 years, and now has developed the whine others have mentioned.  We have 4 sound machines running at night in 4 different rooms, and the other 3 are &#34;older&#34; than this fan, and they are all going strong still.  All were similarly priced, so I am going to steer clear of this brand when I replace my daughter's white noise machine.<br /><br />3 stars because it did the job for the time it lasted.  I don't know how long it is supposed to last, but given how my major appliances only last a few years anymore I would say 3 years for this little sound machine is &#34;ok&#34;.
