Defective but makes nice waves when it works
It did make great waves but it would not stay turned on. I tried watching my hand placement to make sure I wasn't switching it off when using it. After that was unsuccessful I turned it back on and just left it sitting for a couple minutes and viola! it shut off by itself.  It is very lightweight and seems a bit chintzy for the price. I'm returning it and I decided to go with a brand I am familiar with for about the same price. It gets 3 stars because it really makes nice waves when it stays turned on.
