Fitbit Forcechat_bubble_outlineFrom real comments

The clasp and physical durability are the Force's biggest weak points. Numerous commenters cite the locking mechanism as a dealbreaker, with units falling off and getting lost, sometimes attributed to travel or incorrect fastening. The non-replaceable band was also a concern, especially after seeing similar wear issues on the Fitbit Flex. Some suggested retrofitting the band as a workaround, while others insisted it stays secure if properly fastened.

Skin irritation and chemical burn reports raised serious health concerns. Several users reported chemical burns or skin irritation after weeks of wearing the device, with speculation about a bad battery batch or RF radiation exposure. Fitbit reportedly received multiple RMA units for this issue and eventually began offering refunds or exchanges. Others noted proper strap cleaning could resolve irritation, and some users had no problems at all.

Long-term reliability and tracking accuracy drew mixed reactions. Some owners reported screens dimming to unreadable or failing entirely after about a year, with Fitbit customer support denying warranty claims. Activity tracking was called inaccurate for workouts like cycling and stair climbers, since stairs are measured via altimeter rather than actual stepping motion. Meanwhile, the silent alarm and sleep tracking features consistently received praise from users.
