Right to Repair

Score breakdown

Why this grade

Wearables only (no earbuds). Fitbit Versa 4 and Charge 6 both score 4/10 on iFixit: no screws/clips, so reassembly needs custom-cut adhesive, and specialty tools are required to pry up the adhesive-sealed display (tedious and risky). The Fitbit Sense teardown shows the battery is ultimately replaceable and internals are fairly modular, but a heat gun and thin tools are needed just to open it and sensor-board components are permanently glued. No official replacement parts or repair instructions; out-of-warranty units are effectively replace-not-repair.
