Don’t waste your money [SEP] 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.<br />This one is very cheap quality....<br />I wish I had returned it...
