Doc Johnson Vac-U-Lock-adapter for Motorbunny BUCK

The threading clicked right into place with the BUCK base with zero wobble, and now I can swap between Vac-U-Lock toys in seconds flat. It’s made the whole setup feel like a proper system instead of a one-trick pony, which is exactly what I was hoping for.

I was honestly skeptical about adding this to my setup, but the lock-in mechanism clicks so securely that there’s zero wobble even at higher speeds. It’s turned my machine into a whole new toy, and swapping attachments takes seconds now.

The compatibility is spot-on—it locks into the BUCK's thread without any wobble, and the quick-release design makes swapping attachments a breeze. I've used it three times already and it feels solid enough for the thruster's power.
