Please include all comments for the authors in this box rather than uploading your report as an

supporting materials or other aspects of your report which cannot be included in a text format.  
The English must be edited / revised considerably before publication.  
There is a note about confidentiality being maintained by using identification numbers but that 
makes no sense given that interviewers  had to ask for a specific person at a specific address - 
something must be clarified in the procedures to make any of this work.  Either they pulled 
names and addresses from the "list of users) or they didn't and hence had to do a "house to 
house" to scre en for users.  ID numbers do not work for this study protocol unless there is info 
still missing.  The sampling info suggests that they both used a listed sample frame but also 
screened in a house to house fashion - otherwise, there shouldn't have been hou seholds where 
there were no eligible participants.  Either the health registry info was incorrect and the woman 
had moved or they used a household sample with no info about health history - still very 
confusing from the sampling information.   
The analysi s seems to include the notion of satisfaction as a predictor of duration of use - this is 
of little use.  It is self -evident that someone who is satisfied will have a longer duration of use 
than someone who isn't satisfied.  Perhaps there is more to the in clusion of this variable but it 
needs more expansion of utility.  
 
Other findings do add to the literature somewhat.  
Improvements are helpful but modest.
