Review (4/5): Button was giving me troubles.
It is kinda confusing and difficult to start. I hold down the button a couple times and it would not turn on after charging. I feel like the vibration is not very strong. I like another brand of this same type better. This one looks fancy and seems like it would be high quality but Im not sure if it is. I think the buttons are somewhat defective in the model i was sent. I think the light vibrations could help a little so im not saying its completely worthless. Im just saying there are better ones out there
