Sex Machines

What separates these machines is mostly how you control them and how they move. The Lovebotz Thrust Bot is handheld, which keeps the pace in your own hand. The Lux Fetish compact machine is listed as rechargeable and comes with a remote, so someone else can run it, and the Bigger Bang thrusts and rotates, which adds a second kind of movement. Lovense has a Mini Sex Machine, and Evolved has the G Force Thruster.

Adapters and extensions

Lovebotz lists a flexible extension and a dildo adapter attachment on their own, and there are adapters from other brands too.
