Bests & Worsts Reviews from Amazon

First, we bought the dual speed machine. After some trial and error, we only use it on the higher setting. The higher speed is louder/ and masks more noise. When we decided to buy a second one, I took a chance hoping that the single speed machine would be the same as the high speed setting on the dual speed machine. It is! Just wanted to put that out there for anyone else wondering the same thing. Thanks for reading, I hope this was helpful!
