Can anybody identify this device?

This woman appears in many clips, and I've failed to find a device like this anywhere. It's clearly a bluetooth device. Judging by her reactions, it also appears to be e-stim. The clips show her actuating it personally, and it also appears as though it's possible to somehow actuate it by some online means. Here's a clip to illustrate: https://www.pornhub.com/view_video.php?viewkey=ph5896e77ac9c7f

Are these clips just a hoax?

I searched and Googled without success, but there are two differents sounds a sort of bell and like rattle noise this last noise can be coming from a vibrator's motor who is running too fast because the battery is over charged ( personal experience ). I think it is possiblethat it is not electrostim but a vibrating egg monitored by bluetooth or with a common remote control. The buckle rope can be used to slide the egg out of the vagina (anus).

I don't think it is an hoax.

In any case I am so curious as you @fiddlehead to know what it is.
