Fitbit Charge 6 vs Inspire 3: Design

The Inspire 3 borrows its design traits from Fitbit’s fashion-first Luxe tracker, making it one of the more attractive wearables in the company’s lineup. It’s smaller than the Charge 6 and employs a narrower, all-plastic body and a lighter build. Despite its smaller stature, we liked how the Inspire 3 fit on our wrists during our review. The soft-touch bands and minute pill makes the device incredibly comfortable.
