Starting a little confusing and slightly discouraging for that is not used to these accessories (question bluetoth particular). After downloading SamartPukse Free for iPad mini, it works. Except for one, I do not find this very comfortable belt, it must be well maintained at heart level (if I understood correctly) and live on the skin, so bad. I am perhaps a little too hard? works well but it discourages. I'll maybe see a band, and I possibly will modify my review
