SILA™ is a sonic massager built around wave resonance rather than direct surface pressure. Eight wave intensities deliver gentle, broad-coverage stimulation into the surrounding tissue, helping release everyday tension and encourage a calmer, lower-stress state.The soft, contoured head spreads pressure evenly for a comfortable fit against the body, making it easy to build a consistent daily wind-down routine. Crafted from non-porous, hypoallergenic body-safe silicone and fully rechargeable.Please be aware that the packaging you'll receive may vary from the one depicted here.Specifications Materials Body-safe silicone, ABS plastic Size 80 x 75 x 35 mm / 3.1 x 2.9 x 1.4 in Weight 105 g / 0.23 lb Waterproof 100% waterproof Battery Li-Ion 520 mAh 3.7 V Charging 2 h at 5.0 V 500 mA; USB-charging cord User time Up to 2 h Standby Up to 90 days Settings or modes 8 modes Interface 3-button interface Warranty 2-year LELO manufacturing warranty, followed by LELO's 10-year quality guarantee In the box SILA™; USB-charging cord; satin storage pouch; warranty registration card; detailed instruction manual Certifications ISO 3533
