Lansinoh Smartpump 3.0 Double Electric Breast Pump

Background/Usage: I'm an exclusive pumper, pumping 6 times a day for 30 minutes each session. For my first child, I successfully used a Lansinoh 2.0 smart pump for my entire exclusive pumping journey. Therefore, for my second child, I chose the Lansinoh 2.0 smart pump again. I wish the 3.0 was available when I ordered my pump! The rechargeable feature is incredibly convenient; I don't know how I managed without it for my first child. I use the pump on its pre-set settings, although it's easy to change. Let-down mode: suction level 5. Expression mode: suction level 3. I haven't tested how a higher or lower suction level would affect the battery usage. Here's a comparison between the 2.0 and 3.0 pumps: 2.0 pump: - has compartment for 6 AA batteries. Only good for a few 30 minute pump sessions. This is a costly way to stay mobile, so I rarely went on battery power. - After a few pump sessions on battery power, the suction power noticeably decreases. - pump turns off when switching between AC power and battery power - the power button just powers the pump on or off, there is no "pause" button - white and light purple color (fun fact) 3.0 pump: - rechargeable battery already installed. Just need to charge it for 3 hours prior to first use - I recharge the pump after every 30 minute battery-powered session. I have not noticed a difference in suction when I'm on AC power vs the rechargeable battery. (We'll see if this changes over time--I've only used this pump for a few sessions so far.) - pump seamlessly switches between AC power and rechargeable battery pack; the pump stays on and pumping as if nothing happened - power button is used to turn the pump on/off and to pause the session. When I'm done with a session and hit the power button, the pump stops pumping, but the session time stays on the display - white and royal purple color (fun fact; allows me to easily differentiate between my 2.0 and 3.0 pumps) The 2.0 and 3.0 pumps appear the same in these areas: - noise level (quiet) - size and shape (love the handle!) - generous AC adapter cord length - generous tubing length - extra pump parts (duck bill valves, etc) - 3 pumping "styles" to mimic different baby sucking patterns - let-down mode button - back-lit display (back-light only activated once a button is pushed) - pump parts are interchangeable between 2.0 and 3.0 pumps (additional/extra pump parts are easy to find online! I bought all my through Amazon and Walmart, but I ordered duckbill valves directly from Lansinoh; I couldn't find the genuine Lansinoh duckbill valves by themselves anywhere else.)

it's such a great product! I really recommend this for anyone trying to maintain or increase their milk production. it's not as expensive as some other brands ands it's lightweight!
