Fun Factory Duke brings anatomically-optimized dimensions with modern dual-motor engineering that transforms prostate stimulation. The precisely-calibrated 4.5-inch length accommodates different body types, incorporating rechargeable technology that delivers nine distinct vibration patterns. Premium medical-grade silicone construction ensures comfortable insertion for extended sessions.
This prostate massager delivers targeted stimulation through carefully-engineered proportions that accommodate various anatomical requirements. The 4.5-inch insertable length provides optimal reach for prostate contact, featuring a curved design that naturally follows internal contours. The substantial girth offers satisfying fullness during penetration, creating progressive pressure that builds intensity gradually as you move deeper into your session.
Fun Factory's signature innovation centers around dual independent motors that operate simultaneously for layered stimulation experiences. The rechargeable lithium battery powers nine distinct vibration programs, each calibrated for different intensity preferences. Unlike single-motor competitors, this dual-engine system creates complex vibration patterns that pulse, escalate, and synchronize across multiple pleasure zones simultaneously.
The combination of precise sizing and motor innovation creates progressive stimulation that adapts to your body's responses. As the curved dimensions guide the toy into optimal positioning, the dual motors deliver synchronized patterns that intensify contact with your prostate and perineum simultaneously, building toward more powerful climaxes than traditional single-point stimulators.
Position yourself comfortably and begin with external massage around your perineum and anal opening. A good coating of lube prevents friction burn - apply generously to both the toy and your body before attempting insertion. The curved design guides natural entry, so follow the contours as you slowly insert the 4.5-inch length.
Start with lower vibration settings to allow your body to adjust to both the size and dual-motor sensations. The precision dimensions ensure proper prostate contact once fully inserted, so experiment with different angles and motor combinations to discover which patterns create the most intense responses for your anatomy.
Ideal for men seeking prostate stimulation who appreciate both size satisfaction and technological advancement. The 4.5-inch dimensions work well for most body types, offering substantial presence without overwhelming beginners. Advanced users will appreciate the dual-motor innovation that creates more complex sensations than standard single-motor designs.
Perfect for couples exploring male anal play together, as the external controls allow partners to experiment with different vibration programs during intimate moments. The rechargeable system eliminates battery concerns during extended sessions.

Look, I'll be straight with you - the Duke's combination of size precision and motor innovation creates something genuinely different from other prostate massagers. The 4.5-inch length hits the sweet spot for most guys, providing substantial presence without the intimidation factor of larger toys. But what really impressed me was how the dual motors work together. Instead of just buzzing randomly, they create these layered patterns that build and sync with your body's responses. After 15 minutes with the escalating program, I understood why this costs more than single-motor competitors. The rechargeable system delivered consistent power throughout extended sessions, never fading when things got intense. Most surprising was how the curved dimensions naturally guided me into optimal positioning - no awkward adjusting or hunting for the right angle.
