Active Members: The cost to upgrade is the cost of a new membership selection - 6 months, 12 months or 18 months. If selecting 6 months, the member is only charged the cost of shipping the new device and they remain on their current billing cycle.
Trialing: It is a $176 one time fee for trialing members to upgrade. This includes a new 3.0 strap (free) and four months of membership ($44 x 4 months). If upgrading in the middle of a trial, the member must finish the initial trial commitment before moving into the four month of membership paid for with the upgrade.
