Yes! Willow Pumps are covered under a 12 month warranty from the purchase date, and most accessories — Flanges, Flextubes™, Containers, Container Inserts, and all Willow Go accessories and replacement parts — are covered under a 90 day warranty. Sizing Inserts should be replaced upon signs of wear and tear. Since breast pumps are single-user devices, use by more than one person, including purchasing second hand, will invalidate the warranty. Please keep your original proof of purchase from onewillow.com or an authorized retailer as it is required to exercise your warranty.
Willow 3.0 cannot be used with any charger that is not provided with the pump or purchased as an accessory from Willow. Usage of third-party charging accessories is unsafe, may cause serious damage to your pump, and will invalidate the warranty.
