While this is a cute, basic, and travel sized toy, the inability to put much force behind it will make it pretty useless to a lot of people. It does make a nice 'whack' noise when it comes in contact with skin, but it doesn't give the pain or leave a mark to go with the sound effect. If you're wanting a 'dom's first flogger' this is nice, but otherwise get something that you won't outgrow as quickly.
