I purchased this for a daughter who has Multiple Sclerosis . I have trouble convincing her to wear it ALL the time. The wrist band model is helpful and as the non-user of this device I am happy with it. She is getting more comfortable with the concept of wearing it all the time ,,,even ( and especially ) in the shower. She is 59 yrs. old and we are a stubborn family with the need for ideas to be our own . She will get comfortable with this wonderful product . Prior to my purchase she had fallen in the bathroom and remained on the floor for several hours until I had checked on her . Neither she nor I will ever forget that helpless feeling. This product will assure us that that can NEVER occur ,again.
