Letdown mode is for those who want a dry and subtle breast pump. In this mode, the pump doesn't fill your breast with air, but firmly presses it down with the plastic tip. In this mode, you can then simply lift the breast upward and let it dangle for a few seconds before you release the pressure. If you are in the middle of a breast lift, you can just let the pump run for a few seconds to help set the stage for the electric breast pump breast lift operation.
Expression mode is for those who want additional control over the breast lift operation. You'll use expression mode to turn on the suction and open the drains. Then you can simply lift the breast up and down to speed the breast lift operation. If you are in doubt about which electric breast pump mode to use, the operation will still be the same as in letdown mode.
Letdown mode is ideal for those who want a breast lift and are concerned that the process will be too painful. The mode features a "pull-up bar" that you'll sit on to raise and lower your breast. In this electric breast pump mode you'll also see a rear view mirror in the shape of a card that you can flip through to check the state of your breast as you push it upward.
The most important advantage of this breast lift mode is that you'll be able to review your operation as you take the plunge, and flip the mirror to review results as they happen. This is flipbook surgery made easy.
Expression mode is perfect for those who have advanced notice, and are in the mood of having their breast altered in as little time as possible. The benefit of this mode is that there's no reversing back. Instead, you'll just use your electric breast pump head and look forward to changing your breasts after the swelling and bruising has traditionally disappeared.
Whichever you choose, the point is that you have a lot of choices and it is critical to pick the one that works best for you.
