This unit is great for the websites that like to have an audience on social media. The app can be downloaded by your viewers and they can control the device. It uses the "IJOY" app.This masturbator has 9 vibration patterns and 3 speeds for each one, so there are lots of options. I fumbled around with the item as there are no instructions to tell you or show you how to use it. Butt I found something that worked for my pleasure and found the app interesting for others. Very strongvvibrations on all three settings. Is water proof and don't forget some water based lube. It comes with a charging cable but you will need to get a standard USB inverter if you don't already have one. Comes in a nice black box for discretion.
