The Ameda Lactaline Purely Yours offers single and double electric pumping. It uses the same hospital-grade technology as the Ameda Elite, which is used in 50% of UK hospitals. The secret to the success of the Ameda Breast Pumps is due to the two CustomControl™ dials, speed and suction, which allows each mother to tailor the pump’s performance to her own personal needs, for the best comfort and milk flow every time.
