Very experienced user, 3rd machine in over 30 years.
This is my 3rd sound machine made by this company. Works great as the others did. Have used them since the mid 1980s when I worked graveyard shift. First unit died a few years back but other 2 are still working. Needed a second one for my 2nd house so I wouldn't have to keep carrying it with me.<br />Only reason I gave it only 4 stars instead of 5 is the slight modification they made in the raised area surrounding the on/off switch. I don't like it. Not as easy to access the switch this way. Not sure why they changed it, maybe just for appearance. Other than that still a great sleep machine.
Rating: 4 stars
