Top critical review
Excellent sound at first but develops a rattle over time...
August 18, 2017
These machines make the best white noise and are great for sleeping children (I have four of them). However... they don't seem to last very long. I've purchased 7-8 of them in the past 7 years and currently have 5 of them. All of them have some kind of issue. One of them won't work on the low setting, one of them has completely seized up and doesn't work at all, and the other three of them have developed a rattle. I keep spending the $50 because the sound is so good when they work correctly (I've purchased them here and at Bed, Bath and Beyond).
Update: I read a review that mentioned putting some WD-40 on the fan shaft to get rid of the rattle. I understand that opening them voids the warranty (but mine are all older than one year anyway). So, I just spent an hour opening them all up. The amount of dust inside one from 2012 was so gross. Anyway, I cleaned the dust out of them and put WD-40 on them and they are all sounding like new again. Even the one that was completely frozen up is spinning and sounding great. So, I'm currently happy because I don't have to spend more money on yet another sound machine. I'm not sure if this will permanently fix them or just buy me a few more weeks or months. We seriously can't go a night without the machines because we are so used to the white noise. Excellent sound but they seem to accumulate dust inside and develop a rattle over time.
