Best Features

• It works well both plugged in and running on batteries. The battery charge lasts a long time and there is no reduced power when running on battery.
• There are 5 different speed settings.
• It comes with a 28mm flange, and there is also a 24mm and 32mm available separately.
• It has a simulated letdown mode that works great to get the milk flowing. Once the milk has started, you switch to expression mode.
• It can be used as a single pump, or an optional T-connector can be purchased to turn it into a double pump.
• It’s small, light, and great to take traveling.
• Dual voltage so it works in 110v and 240v countries.
• It’s a closed system, which means there’s no contact between the milk collection pieces and the pump. This helps to prevent contamination from bacteria and mold from forming.

Potential Issues

• The tubes and the suction flange can sometimes pop off and become disconnected.
• The collection bottles are very wide and have to be carefully sealed or they will leak.
