Before you buy Fitbit Flex 2
Fitbit Flex 2 is discontinued. Here's what a current alternative looks like.
Fitbit Flex 2 was Fitbit's smallest band: swim-proof, screen-free and backed by Fitbit's social app. The hardware has been retired. Ray is a current screen-free band that adds continuous heart metrics, temperature and light exposure, and it powers itself from light.

The short answer
Flex 2 is only worth researching if you're looking back. If you want a current tiny, screen-free band, Ray is one option.
Fitbit Flex 2 status: Discontinued / legacy.
Side by side
Specs are manufacturer claims and US pricing snapshots, not lab-test results. A blank promise is less useful than a clear tradeoff, so we keep this list deliberately practical.
