I wasn't expecting much when I took this little fella out of the box. It's small, but sturdy and well made. Then you turn it on and are amazed at how much sound comes out of it. Like a BOSE, it's surprising what you can get out of a small package. The volume levels are finely incremented, and it goes really loud if you want it to. The two things I like about the EVO over the regular model is the angled speaker/buttons and the extra two ocean sounds. I'm already sleeping better.
Pros: - Excellent sound quality - Takes up very little space. Put it almost anywhere - Buttons located on top and angled is a nice touch - The fan noises have excellent range and sound exactly like they should - The white noises are varied enough that you'll find just the pitch you want - A headphone jack - Ability to power it from USB or AC
Cons: - No lights. But it's a basic model, so I wouldn't expect them either - If you pull the plug without turning it off, the last settings are lost - Not rechargeable and needs to always be plugged in. Could be an issue when travelling
