How the grip and vibration work
Hold the side pressure pads to vary squeeze and suction as you move the product by hand. The powered control cycles through six vibration modes. Begin with light hand pressure and a low vibration setting, then increase only while the fit remains comfortable and the product can be removed easily.
First-use and fit check
- Read the included manufacturer directions before charging, cleaning, or using the product.
- Inspect the housing, sleeve, seams, controls, charging port, and cable. Do not use a part that is torn, cracked, unusually sticky, swollen, leaking, overheating, sharply damaged, or exposing wire.
- Use only lubricant that the included directions identify as compatible with the TPE sleeve.
- Do not force the product onto a painful or restrictive fit, and keep the controls within easy reach.
Stop and remove the product promptly if you feel pain, numbness, coldness, burning, unusual swelling, discoloration, pinching, or difficulty removing it. Release pressure before removal rather than pulling against suction.
Cleaning and drying
Power the product off and disconnect it from charging. Open the sides so the sleeve is directly accessible. Follow the included directions for any permitted removal, cleaner, water exposure, and reassembly. Until those directions confirm a water-resistance boundary, keep the powered housing, controls, cable, and charging connection dry and never submerge them.
Clean every permitted sleeve surface after use, rinse only the parts the manufacturer allows, and let all washed surfaces, seams, and hidden channels dry completely before reassembly, charging, or storage. Do not close a damp sleeve inside the housing.
Charging and storage
Charge only when the product and charging connection are clean and completely dry. Use the supplied or manufacturer-approved USB-C cable and power source, and do not use the product while it is charging. The available exact sources do not publish a verified charge time or runtime, so follow the indicator and timing instructions supplied with the product.
Store the clean, dry product separately in a cool, ventilated place away from heat, direct sunlight, sharp objects, dust, and prolonged contact with other soft materials. Follow local electronics-recycling rules at end of life.
