With the extended warranty that is independent of the purchase date, Ardo is the only manufacturer to offer a full functionality guarantee for an average pumping time sufficient for feeding at least two infants. The vacuum and cycle can be individually adjusted at any time. Operation is possible with batteries and a mains adapter. It features a breast shield of 26 mm. Maximum safety, hygiene, and protection against pathogens and contaminants are ensured by the "VacuuSeal" technology. OptiFlow actively massages your breast thanks to the air chamber system and the thin flower windows, providing efficient and comfortable pumping in conjunction with the particularly gentle suction behavior of the Calypso. Its appealing and compact design, along with quiet operation, allows for discreet pumping. It can be converted into a double breast pump with the "ARDO UpgradeSet.".
