Kink - Silicone Vac-U-Lock™ Wand Attachment

Hey all. Does anyone have one of these and does it work well with the Vac u lock dildos?

I'm afraid I don't know much about this particular product, but I'll happily give this thread a little bump to see if you can get some more replies. 🙂

Is it this Doc Johnson one?
