I purchased a brand new fitbit charge 2 that was was dead in the box. Their corporate office told me to return it by mail. They said they would replace it with a Charge 3 because they no longer had Charge 2s. What I got was REFURBISHED Charge 3. When I told them I would like a refund instead of a USED product, they got pushy and said, "That's too bad"! They said there is nothing they can do. Fool me once, shame on you, fool me twice, shame on me! Never again, fitbit!
