Primary Outcome Measures

Name	Time	Method
Likelihood of continuing to wear DT1	3 weeks	A Likert questionnaire will be used to determine patient-reported outcomes -50 being uncomfortable and 50 being extremely comfortbale
Overall satisfaction while wearing DT1	3 weeks	A Likert questionnaire will be used to determine patient-reported outcomes. With answers that are positive such as strongly agree to product satisfaction are better.
