Review on ANCOOL Compatible With Vivofit JR Bands Wearable Technology by Dana Mahendra

My son had a vivofit jr for a year and the original strap ended up breaking. So I went to the trusty Revain to get myself a new tape. On the first day of wearing the new band, the tracker fell out twice. We decided this group sucked (the original group never had this problem) and kept adding to vivofit until we found a new group. Unfortunately my son found it (because he loves his vivofit) and wore it to school. Boom! Lost my fitness tracker, but at least we still have an empty bracelet. Terrible product design! Our original group went through crazy attritions like baseball, football, basketball and swimming in the sea. Stay away as this purchase will cost you MUCH MORE.
