GENEX GX4 is a large-format smart automatic stroker built around powered thrusting, dedicated ball-zone vibration, dual-handle control and connected app features. The removable textured TPE sleeve provides the contact surface, while the foldable handle design gives users more control over positioning and storage.
Automatic Thrusting & Ball-Zone Stimulation
The GX4 uses a powered 40 mm thrust stroke with a rated 160–230 strokes per minute. Separate external vibration contact points add focused stimulation around the lower opening area.
Long-Stroke Drive & Textured Sleeve
A 118 mm internal channel and textured TPE sleeve are designed to increase contact across a larger portion of the sleeve. Use a compatible water-based lubricant with the TPE insert.
Dual-Handle Control
The wide folding handles support two-hand positioning and keep the main controls within reach during powered use.
1.54-Inch Control Display
The built-in display presents operating information such as battery status, mode level, frequency and session timing in one place.
Monster Party X App Features
Compatible app functions shown in the manufacturer materials include remote device control, story-style interaction, AI character features, adjustable speed and waveform libraries. App availability and individual features can vary by operating system, app version and region.
Remote & Connected Control
The manufacturer app materials also show long-distance sharing and compatible-device synchronization features. Availability depends on the connected phone, app version, supported devices and network conditions.
Fold-Away Storage & Exterior Care
The handles fold inward to reduce the device footprint for storage. Wipe the electronic shell clean rather than immersing it. The removable TPE sleeve is the washable contact component.
