Frequently asked questions
How does the Zolo Back Door Cup create suction without a pump?
The cup's construction creates mechanical vacuum around the shaft during insertion and stroking. The air control hole allows the user to modulate this suction in real time by covering or uncovering it.
How do I adjust the tightness of the Back Door Cup?
Cover the air control hole completely to maximise suction and tightness. Open the hole to release pressure and reduce the suction sensation. Partial covering provides levels in between.
Is the Back Door Cup pre-lubricated?
Yes. The canal comes pre-lubricated for immediate ease of entry on first use. Adding additional water-based lubricant is recommended for the best experience.
Is the Zolo Back Door Cup travel-friendly?
Yes. The compact cup design is suited to travel and discreet storage.
