The stroke depth (the distance the arm travels per movement) differs per model:
- Eroticon machines (Khalifa, Jeremy, Love, Reid, Eden, Rhoades and similar models): approximately 7 cm, fixed.
- Gigolo sex machine: adjustable from 2.5 to 15 cm.
- Pro sex machine: 6 different stroke depths to choose from.
The stroke depth is independent of the length of the dildo: a longer dildo does not make the movement deeper, but does determine how far the machine can be positioned from you. Each product page lists the exact specifications and the included attachments.
