I purchased bracelet for both Mom and myself. We have ordered replacement ones at the appropriate time for both. Customer Service has been wonderful and quite responsive with any questions/issues I may have had. The bracelet is an attractive piece of jewelry and we have both rec'd many compliments and questions on it! It gives a nice sense of security. I test both pieces every month to 6 weeks and love the fact that GPS gives location if emergency is triggered. Hope to never need but feel more comfortable having this!
