Review (1/5): Don’t waste your money
Please note that there are two models: one that requires batteries and one that doesn't. The one that doesn't only needs to be charged before use. Hold the button down for a while in order to get it to turn on. Having said that, this is not nearly as good as one (another brand) that I had previously purchased and that Amazon no longer carries.
This one is very cheap quality....
I wish I had returned it...
