Haven't used . Christmas Gift

Wife and I love it !

Its not the most quiet one , but works great. And as far as charging it, it comes with a usb charging cable and u plug it in to the bottom of the thing, pretty easy to do ;) If in doubt, buy it. Cant go wrong with this.

Would like to have kept the product but it has no instructions or any instructions online can be found on how to charge it and no visible charging port for the USB to be plugged in nor did it come with a cord this makes it useless

Had on charger for hours and hours.. no motor noise or sensation/ vibration at all
