I look at Milli like having my own physical therapist at home. And I can have it forever, and do it myself.

I love the concept that any time I have a spasm or pain, I now look forward to using my dilator. Having Milli is like having my own therapist at home..I keep gently expanding it and it helps stretch the muscles in a way that other dilators cannot…I can’t live without it now. I have become so dependent on it and am so grateful it exists.

Revolutionary Technology: Insert Then Expand

For the first time with a dilation device, women can let their bodies dictate how gradually they expand Milli. Women insert the device when it is closed, and then control the wand expansion one millimeter at a time. In this way. the dilation therapy is more attuned to a woman’s anatomy and how she feels.

Gradual Dilation Creates Confidence

Because dilation is changed in millimeters and not centimeters, women can set the device to the diameter that is right for their bodies each time they use Milli. More gradual dilation enables less pain, and women are more confident in their ability to execute their clinically recommended dilation therapy. This may be why 9 out of 10 women surveyed prefer Milli to static dilators.

The women who have used Milli report that they stick with their recommended therapy and are not worried about pain the way they were with static, plastic dilators because they insert Milli at its smallest diameter every time.
