We, at KegelToner.com wanted to be the first to show you the incredible results of a recent comparison study.  The study was performed at Cook Spring Co., a large and respected manufacturer of precision springs that has been in business more than 45 years.  (Cook Spring Co. produces the springs used in the KegelMaster 2000).   The measurements were made using a Chatillon Spring Force Tester model DST 80.  Anyone with adequate measurement equipment should be able to produce similar test results.  

RESISTANCE SETTINGS: 

  You may not know it, but a wide variety of devices have been invented in an attempt to better exercise pelvic floor muscles.  However, the KegelMaster 2000 is the only pelvic floor exerciser that uses four springs to provide 15 different resistance levels, as shown above by the pink bars.  No other device comes close.  These resistance levels, entitled "Muscle Strength" on the chart, range from 1.22 to 7.8 lbs. when the unit is closed to within 1/8 inch from completely closed.(1)  Both the range of resistance and the number of steps are very important because each women's vaginal strength is different.  Feedback reported to KegelMaster 2000 Ltd. indicate that many women need to start at the lowest resistance setting, then gradually strengthen their muscles up to resistance setting 4 or higher in order to achieve the desired results of stopping incontinence and/or improving their sex life.

   A product that looks similar to the KegelMaster 2000 has recently been promoted.  It's results are shown by the blue bars on the graph above and we think the chart speaks volumes.  The competitor's product  may look similar in appearance but the resistance levels (muscle strength needed to close the unit) are not.  Since it uses only two springs and those springs are in close proximity to each other, only three resistance levels are obtained and all of those are of  low strength.  In fact, in seven women that had been using the KegelMaster 2000 for at least 6 months, the competitor's product could not produce enough resistive force to extend their vaginal muscles.

RANGE OF MOVEMENT:

   Another important difference in the products has to do with the range of motion they can apply to the vaginal muscles.  The KegelMaster 2000 has a threaded screw and knob to adjust the opening of the device from completely closed to open 2 5/8 inches.  Since every women is different due to how many vaginal births they have had, their age, unique physical anatomy, etc., each woman needs a different adjustment in order to maximize her benefit from the product.  For example, women that have had 3 to 4 children by natural birth often need the full 2 5/8 inch extension before they feel gentle pressure against their vaginal muscles.  This gentle pressure is recommended to KegelMaster 2000 customers as the starting point for their contractions and is believed to provide the best benefit to muscle development.

   The competitor's product has three fixed openings that are controlled by an o-ring positioned in one of three grooves.  It opens to approximately 1/2 inch, 3/4 inch, and 1 1/4 inches for the three settings.  According to women who have spoken with KegelMaster 2000 Ltd., this amount of opening would be insufficient to provide any measurable benefit to them.

CONCLUSIONS:

   Every woman is physiologically unique and needs a product that can adjust to her body.  The KegelMaster 2000 is the only pelvic floor exerciser in the world that can provide a full range of adjustable resistance settings up to 7.8 lbs and a 2 5/8 inch range of motion that is completely and safely adjustable.  This wide flexibility results in a product that is best able to meet the individual needs of each woman.  To date, no other product comes close. 

Notes:
(1)  Less resistance is required to partially close the device as opposed to completely closing it.  This means that the actual number of resistance levels is almost limitless between 0 to 7.8 lbs.
