Product Description

Meet the all-new Fitbit Flex 2—a slim, swim-proof fitness wristband that's ready to go wherever life takes you. The ultra-thin, removable tracker hides in bands, bangles and pendants, so you can wear it in a way that's all your own. Automatic all-day activity and sleep tracking show you how your entire day adds up, and SmartTrack automatic exercise recognition records your exercises for you. The discreet progress display uses color-coded LED lights to keep you connected to calls, texts and Reminders to Move. Plus you don't have to worry about getting it wet—whether you're swimming in the pool or running in the rain. It's the next generation model of our most iconic tracker. No fuss, all fun, and fit for every you.

Seller marked up price!!  See proof.
1 Star
Seller marked up price!! See proof.
The 1 star is for the SELLER, not the product.This is a replacement for the same version that I essentially wore out 🤣So I was seeking this particular model which I know is a little outdated but I prefer it’s slimline band.It was more expensive (double) the cost of my original Fitbit but imagine my surprise when the box arrived with a 29.99 sticker on it. That’s exploitative!!!
