Hi This is not my method, just wanna point that out the owner is apart of a different forum.
Let's get into it.
1. So go find an Moov you want to SE.
Like Moov Now - Stealth Black - 3D Fitness Tracker & Real Time Audio Coach - [NEW] Run Walk Swim Cycle Workout Cardio Boxing for example.
2. Email them (Email[email protected]) and say "My Tracker won't turn on"
3. They will ask for proof of purchase just fake an Amazon invoice (They won't validate it)
4. They'll give you a promo code sort of thing enter it at the moov store for a replacement core
*Does not come with band, buy one off of ebay*
